Stanford’s latest breakthrough: logical door calculation is super simple with light quantum!

Today’s many quantum computers are complicated, it is difficult to expand the scale, and it is necessary to run more colder than the interstellar space.These challenges cause researchers to explore the possibility of constructing quantum computers operating using photon (photon).Photons can easily transfer information from one place to another, and photonic quantum computers can operate at room temperature, so this method is very promising.However, although people have successfully created a separate quantum "logic gate", a large number of logical doors are constructed with photons and connect them in a reliable manner to perform complex calculations, or a technical problem.

Recently, Stanford University researchers have proposed a simpler photon quantum computer design, and can be used along the ready-made components. According to a paper published on Journal Optica on November 29, they proposed using lasers to manipulate individual atoms, while individual atoms can modify the state of photons by a phenomenon called "quantum invisible path". The atom can also be reset and reused in many quantum doors, so that there is no need to construct a plurality of different physical doors, which greatly reduces the complexity of constructing light quantum computers.

"Normally, if you want to build this type of quantum computer, you must use thousands of quantum transmitters to keep them perfect, then integrated into a huge photon circuit," application physics doctoral student The first author BEN BEN BARTLETTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTLET, and we only need a few relatively simple components, and the size of the machine does not increase with the size of the quantum program you want to run. " A very simple design requires only several devices: fiber optic cable, beam splitter, a pair of optical switches and optical cavities.

Fortunately, these components already exist and are already commercially used and continuously improved because they are currently used in quantum calculations. For example, telecommunications companies have been committed to improving fiber optic cables and optical switches. "The proposal of this program is based on people’s efforts and investment in people who have made these components. The professor of Stanford Engineering, Shanhui Fan, senior author of the papers. "They are not new components specifically used for quantum computing."

New design

The design of Stanford scientists consists of two main parts: a storage ring and a scattering unit.The function of the memory ring is similar to the memory in the normal computer, which is a fiber loop including a plurality of photons propagated around the loop. Similar to the bit of storage information in the classic computer, in this system, each photon represents a quantum bit. The photons determine the value of the quantum bits around the traveling direction of the storage ring, which may be 0 or 1. Further, since the photon is in the superimposed state, a single photon can simultaneously flow in both directions, which means the value of the combination of 0 and 1.

Figure 1. Photon quantum computer architecture described in this work.

(a) Physical design of the equipment. The photon quantum bit is reversely propagated by the fiber storage ring, and the optical switch can selectively guide the photon interaction with the atomic interaction in the cavity by the scattering unit, and the cavity is coherentiated in the cavity.

(b) The energy structure of the atom: ω1 is resonant to the cavity mold and the photon carrier frequency, and ω0 is far apart.

(c) the description of the BLOCH sphere on the photon quantum bit state {|?, |?} foundation and an operation applying the scattering unit. About rotation

Progressor and beam splitter apply a fixed angle (gray), and rotate

Apply a cavity laser using a lumen laser using a controlled angle θ (pure red). The projection measuring atom transmits this to the photon, but may exceed the target angle θ through π (red dashed line) depends on the measurement result m. ??This operation is a universal original single quantum bit: By combining multiple such operations, and The subsequent rotation angle is adjusted according to the measurement results, and any single quantum ratio can be determined.

The researchers can manipulate photons by directing photons from the memory ring to the scattering unit, where it propagates to cavities containing a single atom. The photon is then interacting with atoms, resulting in "entanglement", which is a quantum, and two particles can even affect each other at a very far distance. Then, the photon returns the storage ring, and then the state of the atom is changed again. Because the atoms and photons are entangled, the operation of the atom will also affect the state of their pairing photons.

Figure 2. Quantum gate sequence corresponding to photons pass through the scattering unit. The projection measurement will be transferred to the photon quantum bits to the rotation of atom quantum bits.

"By measuring the state of the atom, you can transfer the operation to the photon," Ben Bartlett said. "So we only need a controllable atom quantum bit, we can use it as a proxy to indirect all other photon quantum bits.

Because any quantum logic door can be compiled into a series of operations performed on a single particle, in principle, you can use only one controllable "atomic agent quantum bit" to run any size quantum program. In order to run the program, the code is converted to a series of operations, which guides the photon to the scattering unit and manipulate the atom quantum bit. Because you can control atoms and photon interactions, the same device can run many different quantum programs.

Figure 3. Conceptual diagram of the instruction sequence to compile the quantum circuit into the device to be executed on the device.

(a) Universal target quantum circuit.

(b) Decompose the equivalent circuit and the CσZ door of single quantum bit.

(c) The circuit is further decomposed into a series of scattering interactions. This sequence can be assembled into a command set on the classic computer, including six different primitives corresponding to physical actions.

(d) The controllable elements of the quantum device are optical switches, cavity lasers and atomic states.

"For many photon quantum computers, the physical structure passed by photons represents different logic doors, so if you want to change the running program, it usually involves physically reconfiguring hardware," Bartlett said. "And under this new design, you don’t need to change hardware, just need to give a different set of instructions for machines."

What is the millennium? A huge bug left at the beginning of the birth of the computer

To put it, in addition to social technology, in addition to truly learning computer professional, most people have some strangers for "millennium insects", even some people have never heard, do not know, users hear "insects" This word may also make a large pile of unidentified creatures, but in fact, "millennium worm" is not a creature, but a computer system created by humans.

The birth time of "Millennium Worm" is far from a so-called 1000 years. In fact, it is concerned that it is 21 years ago, and "Millennium Worm" is not like the netizen imagination, it is a similar "panda burning incense" Computer viruses have caused significant losses to humans at the beginning of the birth of the computer. It is exactly that it is a loophole of computer system designers, which is the system we are well known. "BUG"

Bug mother "Ge Lisi Hope"

Speaking of the history of the millennium has to mention a person, her name is "Ge Lisi Hope", people who have learned computer history should know that she has an outward in the computer field, called "BUG mother "

Geleis Hop was born in the United States in the United States in 1906, from a small way, especially the talent of math, in 1928, Hoop, who graduated from the Vasa College, has obtained the double bachelor degree in mathematics and physics. Later, she continued to study, six years later, becoming a small female doctoral mathematician, after 1939, the Second World War broke out, Hop was affected by the social environment, entered the US Navy system

Although Huof can’t kill the enemy because of women’s identity and physical problems, Hop is unable to kill the enemy. And sent to Havende Aiken’s hand as an assistant, and Howard is the manufacturer of the first general computer "Mark No." "Mark No." later.

Hop remained in the computer industry, Hop remained in the computer industry, because of the super high mathematics talent, her understanding of the knowledge of computer systems quickly, and became the most effective way of Howard’s hand, one is in progress "Mark 2" "In the operation experiment, the machine is inexplicably fault. Scientists find everything after the equipment, or Hop thought is fatigue, and found that there is a small bug in the computer system board, and she writes in the job note" because of a bug " (English in English), we interrupted the experiment "

This is the first "BUG" of the computer system in history. Hop is not only the first person who uses BUG to call the accident, but the earliest scientist manufacturing bugs for future generations.

"Millennium insect"

In 1957, after the end of the Second World War, countries around the world began to develop science and technology, and the research and development of computer systems in the United States has become flooded. The programming language has no uniform system, so the institution at the time. Invited Hope, I hope she can develop a general computer programming system, which is the COBOL language, which can write large-scale load procedures.

In addition to the changes in programming language, Hop is also significantly adjusted on the computer storage system. She is the world’s first developer who chooses 6 digits to store the date, like the count date we use 96.10.18 The representative is October 18, 1996, Hop is the starter of this counting method.

However, even Hope did not expect that she changed a small change in the date storage system, which actually triggered the world’s global system bug.

The principle of this bug is very simple, that is, the 6-digit storage date method, although some computer runspace, but every time you go to the millennium, the system will not recognize the problem, such as 6 digits in 2000 To store, it is 0000 years, and the intelligence of the computer at that time is not recognized that the month is 2000 or 1000 years, which leads to a major deviation in some calculation results.

Not only that, because the electrical system at home and abroad is already popular in 2000, and most of them use Hop-developed 6 storage methods, they have encountered bugs, and this will have once every 1000 years. The computer vulnerability is called "millennium insect"

Interestingly, when Hop-developed 6 stores, the United States "Bob" has discovered its major bug, but the people at the time did not think about it, because they think this vulnerability is a born year. I can’t encounter, so I am too lazy to solve, but it is better to hand it over to the future generation. I have not been released until 1990. The programmer in the world has not been released, so in the past 10 years, it is collapsed for the system. prepare for

Until 2000, the vulnerability of the millennium insects officially broke out, although many computer systems have collapsed, but it is better to prepare, so the impact of "millennium insects" is not big, and it has been in the past 20 years The engineers are constantly improving, even if it is once again outbreak, wait for 3,000 years, people still use it without a computer.

It’s just that we can’t be sure. In today’s less improved today, we will also have some "millennium insects", and do not want to improve after discovering, so that it will resolve the future generations?

Glory 60 is about to be released: the release will become a fashion show, super perception VLOG is worth looking forward to

Under the influence of "two-wheel drive" research, glory accelerate technical reserves and model research and development – the number of digital series, upgrade to the "one year of the two generations" release rhythm, and will bring a strong cross-level experience that is strong. This is not, the glory 60 series will meet with us tomorrow (December 1).

Glory 60 has not sent fire, or will become 2021 color ceiling

Glory Digital Series, has always been a "tide value" and "trend VLOG". Single saying appearance, glory 8 charm sea blue, glory 9 seagull gray, glory 10 Aurora gradation, glory 20 Icelandic illusion, glory 30 titanium empty silver, glory 50 ring design … Every generation of design has left a very profound memory point. With fashion avant-garde expression, the glory digital series can lead the latest charm trend in the industry, becoming an aesthetic benchmark for the industry.

Therefore, when the glory 60 series appearance is exposed, it attracts the attention of many media and consumers. The design of the Glory 50 Series double ring rear camera is continued, and the back cover of the white and blue graduated body. Shining stars, maybe suggest that glory 60 Series fuselage will join Star Diamond Process, which is 2021 smartphone colorful ceilings, or will lead 2022 to the first half of the year.

Super perceived vlog artifact, empty gesture is very creative

Image Aspect, this glory 60 series or will launch a new feature "empty VLOG": After the palm of the palm, the glory 60 series has a sign of palm identification; make a fist, flip, OK, etc. Different gestures, glory 60 series There is also a functional change. It looks simple features, behind the glory terminal is rich in technology research and development.

For example, the camera of the glory 60 series wants to identify the relevant gestures (holding boxing / flipping, etc.), involving osteoarth-recognition, humanographic identification, chip optimization, integration, etc. Considering that the function cooperates with the front camera’s VLOG recording, it means that the glory 60 series is recorded while the video is recorded, and the difficulty can be seen. However, glory technology has supported the landing of glory 60 series, providing more possibilities for Vlog shooting.

According to the current exposure, it is not difficult to see: the glory 60 series, continuing "Tide Beauty Value" and "To force Image" two points, is a high-end series with elegant tide medium. Under the blessing of overflow technology, the Glory Digital Series realized the goal of "two generations of one year, strong generations". So, "The annual heavy burst model" glory 60 series will surprise, how much is the price? On December 1, the new product was released, we didn’t see it.

Shang Dynasty Technology By the Cosmic Cosmic Ai First Stock, how would Shang Tang Technology in Hong Kong stocks?

In recent time, Yuancos is the most red hotspot in the current market. In this context, from technology companies to sports consumer goods brands, almost, which companies are reluctant to miss the wind of the Yuan Universe, but they are in this wind. A company has to borrow the Yuan Coso to become the first share of Hong Kong stocks. This is the famous AI four small dragons. How does Shang Tang Technology will go in Hong Kong stock?

First, Shang Tang Technology heard through the Hong Kong Stock Exchange?

According to the report of Shenzhen News Network, recently, artificial intelligence software company Shang Tang Technology has passed the HKCO’s listing and updating the information set after hearing, and HSBC is a joint sponsor.

The present invention shows that as of June 30, 2021, the various cash and deposit reserves of Shang Tang exceeded 19 billion yuan, and the accumulated revenue of 9.98 billion yuan in the first half of 2018-2021.

Among them, Shang Tang Technology has revenue 1.652 billion yuan in the first half of 2021, and the same period last year was 861 million yuan, a year-on-year increase of 91.87%. In the first half of the year, it lost 3,713 million yuan. Last year, the same period was 5.33 billion yuan. Non-international financial reporting guidelines were adjusted with a net loss of 1.726 billion yuan. The same period was 110 billion yuan last year, which was over-lost year-on-year. According to Shari’s industry report, based on 2020 income levels, Shang Tang has become the largest AI software company in Asia.

The statement shows that Shang Sang’s business covers smart business, smart cities, wisdom life and smart cars, and supports AI model production and software development in various fields through a unified AI infrastructure. Prospective disclosure, 2018, 2019, 2020, in the first half of 2021, Shang Tang Technology’s gross profit margin was 56.5%, 56.8%, 70.6% and 73.0%.

Shang Tang Technology was established in 2014, is an artificial intelligence (AI) software company. Shang Dynasty Technology and Headlight Technology, Yunzheng Technology, AI Entrepreneurial Company in the three visual fields of Technology, is known as "Ai Four Small Dragons." This is also the origin of "AI Si Xiaolong" concept.

Different, after a few years of development, from the technical concept to product service, "Ai Si Xiaolong" has its own positioning and development direction. Old Big Brother Dang Technology adheres to the AI ??platform-type service route, the scientific and technological pioneer AI IoT, according to the field of medical equipment, cloud from technology, focusing on human-machine cooperative operating system.

However, in the prospectus of Shang Dynasty Technology, there is a concept that has triggered the extensive attention of the market. In the hearing information, Shang Dynasty technology has 47 times mentioned "Yuancos", 42 times of the first submission of application materials, more out 5 times. It can be seen to the "Yuan Cosm". In addition, Shang Tang Technology is self-told in the hearing, and claims to be "Asia’s largest metacharities". "

In the present invention, Shang Tang Technology said "Our Sensemars has become one of the largest metacharities platform in Asia, is the first artificial intelligence company that helps mobile applications to implement interactive enhancement reality and mixed realistic effects."

Second, how would Shang Tang Technology in Hong Kong stocks going?

In the face of Shangshui Technology through the Hong Kong Stock Exchange, and the large-scale borrowed the universe, many people are in questioning the Dang Technology to do what? How will Shang Tang Technology walk in Hong Kong stock? In fact, in September, we used the article "Shang Tang Technology sprint listed in the research" Shang Tang Technology sprint, and the four small dragons have been going on the road, the future, what should I see? "Discussion on the development of the business soup technology, but at that time, the Shang Tang Technology did not have such a big medal in the universe, this time we may further study, where is the road of Shang Tang Technology in Hong Kong?

First of all, Shang Tang Technology has a certain leap-forward service capacity as the first of the four small dragons. According to the Third Party Advisory Agency, Frost & Sullivan reports, 2020, by income, Shang Tang Technology is the largest artificial intelligent software supplier in Asia, and has become China’s largest computer vision provider with 11% market share. As of June 30, 2021, the number of customers in Shang Dynasty software platform totaled more than 2400, covering 250 "wealth" 500 companies and listed companies. Our foregoing has said that in the four small dragons in Ai, Shang Tang Technology still adheres to its own AI platform-type service route, and in the AI ??platform service, Shang Dynasty technology has already made a good market development, at least A certain customer base, this foundation helps Merchants Soup technology have a certain degree of leap-forward service capabilities, which should belong to the basic disk of Shangshui Technology to be available in Hong Kong stocks.

Secondly, the Yuan Coso, which is borrowed by Shang Dynasty, has its own people. When the first metamorosis was popular, we have repeatedly said that from the moment, there are more or less problems with most of the company’s development of Yuancos, and the technical reserves of major companies are not enough to support a perfection. Yuancosystem, the conceptual characteristic of the Yuan Universe far exceeds the general real floor characteristics, but after we carefully study the prospectus of Shang Dynasty Technology, it was found that Shang Dynasty technology is indeed the fastest in the Yuancai market. One of the companies. We found in the prospectus of Shang Tang Technology, Shang Dynasty Technology is a Yuancai Scene built using the SENSEMARS platform, builds three core elements of SenseMars Reconstruction, SenseMars Avatar and Sensemars Agent, where SenseMars Reconstruction You can build a projection of our current real universe in the metamorphic model in the metamorosis, thus building the scene of the universe. In the Yuancosian, SenseMars Agent generated software intelligent body allows users to interact directly with people in the universe, and can say that the emergence of these three core elements has gradually become a possibility that the construction of the universe from a virtual concept. Things, Shang Dynasty technology has indeed a way to borrow a Yuancosian, and Shang Tang Technology is also one of the companies that can take out the real-feasible solutions in China’s technology companies.

Third, the long-term risks of Shang Tang Technology have also existed. With platform-grained service capabilities, Shang Tang Technology has built its own business fundamentally, with the SenseMars platform, Shang Tang Technology has gone out of his own steps in the Yuancosian field, these achievements are enough to let Shang Tang Technology to the capital market, but Although it is easy to go, it is not so easy, and the risks of Shang Tang Technology also exists:

First, the loss problem will never be eradicated. Shang Tang Technology 2018, 2019, 2020, in the first half of 2021, net loss is RMB 3,433 million, 4.968 billion yuan, 12.158 billion yuan and 3,713 billion yuan, it can be said that Shang Dynasty technology’s loss has become one It is often said that we have always said that the short-term loss of technology companies is not a problem, but such a large-scale loss capital market has an unknown number.

Second, the Yuan Cosmic Concept is good, but it can’t make money in a short time. We saw the system of Shang Tang Technology, the Yuan Universe can only be said to be a bright point but is not the main business of Shang Dynasty technology, but it is this brightest growth point. The Yuan Dynasty in Shang Tang Technology is only only It is a long way to take the first step, and the distance from the truly landing is very difficult, while the other business is very far away from the distance of smart business or smart city, which is very far away. This may be a business soup. The biggest problem of technology.

Third, increasingly fierce market competition will exacerbate. For the business soup science and technology, although Shang Tang Technology occupies the first place in the four small dragons in Ai, don’t forget to do Ai, more than four small dragons, the majorities in the market are rubbed, including many giants, once these giants are all After in person with you, the competition in the entire market will undoubtedly be more intense.

Therefore, the current Shang Tang Technology is not easy to go on the Hong Kong stock road, but it is more difficult to go, this requires the business soup technology to do its own business.

Bed length artificial intelligence tutorial free expansion 130 – true and false

Friends, if you need to reprint, please indicate: [] (

Disclaimer: During the teaching of artificial intelligence technology, many students will mention some Python related questions, so in order to let students master more expanded knowledge to better understand the AI ??technology, I will let the assistant responsible for sharing this Python series tutorial, hope Can help everyone! Since this Python tutorial is not written by me, it is better to teach humble as my AI technology, and learn to be boring; but its knowledge point is still a bit, and it is worth reading! Classmates who want to learn Ai technology can click to jump to my [Teaching Website] ( PS: I don’t understand this article, please see the previous article first, and gradually gradually learn every day, I will not feel difficult!

In Python, like most programming languages, integer 0 represents false, integer 1 representative. However, in addition, Python also treats any empty data structure as a false, regarding any non-air data structure as true. The concept of true and fake is inherent attributes of each object in Python: Each object is not true, as shown below:

? If the number is non-zero, it is true.

Other objects are true if it is not empty.

Python has a special object: None, it is always considered to be fake. This is a special data type in Python, which plays an empty placeholder, similar to the NULL pointer in the C language.

You can initialize a list with 0, but if you still don’t know the content of the list, use None more appropriate:

“ `

>>> l=[none] * 100

>>> L


“ `

Python’s Boolean BOOL is just a custom version of integers 1 and 0. Such a design is to make the true value more clear.

Python also provides a built-in function BOOL that can be used to test a Boolean value of an object:

“ `

>>> BOOL (1)


>>> BOOL (‘spam’)


>>> BOOL ({})

Pakistan seals T20 sweep over Bangladesh in Dhaka thriller

Pakistan completed a clean sweep over Bangladesh in their Twenty20 series, winning the third and final game by five wickets after a thrilling last over on Monday.

Bangladesh totalled a mediocre 124-7 on a two-paced wicket that had variable bounce, but a slow approach meant Pakistan needed eight runs off the final six balls.

Captain Mahmudullah came on to bowl his only over of the day and dismissed Sarfaraz Ahmed and Haider Ali in consecutive deliveries before Iftikhar Ahmed smashed a huge six off the fourth ball, denying him a hat-trick.

With two runs needed off two balls, Iftikhar went for glory but ended up being caught for six at backward point. New batsman Mohammad Nawaz then hit a four through extra cover to take Pakistan home.

Mahmudullah finished with 3-10 from his solitary over.

“The pitch was a tricky one,” player of the series Mohammad Rizwan said. “Whenever you play away, you get on different kinds of pitches. But we try to stick to our process.”

Earlier, Haider and Rizwan had put on 51 for the second wicket for Pakistan.

Paceman Shohidul Islam, making his debut, picked up his first wicket by removing Rizwan for 40. But Haider appeared to be in full control, hitting 45 in 38 balls with three fours and two sixes before falling.

Mahmudullah had opted to bat first but debut paceman Shahnawaz Dhani, leg-spinner Usman Qadir and fast bowler Mohammad Wasim claimed two wickets apiece to restrict Bangladesh to its low score.

Dhani took a wicket in his first over by removing Najmul Hossain Shanto for five. Mohammad Naim ended up as the top-scorer for the home team with 47 off 50 balls.

“Batters from both sides struggled,” Mahmudullah said. “You need to spend time at the crease before you can capitalize. Naim batted well.”

Pakistan won the first game by four wickets and the second by eight wickets.
