Chinese Scientists Make Breakthrough in Quantum Computing

Good, I do remember the new benchmark to measure the power of a quantum computer is about the quantum bit.

So China will have 50 quantum bits by 2020, and 100 quantum bits by 2025 as Dr. Pan aforementioned several years ago.

SCMP says in its report “China hits milestone in developing quantum computer ‘to eclipse all others’” yesterday that Chinese scientists have built world first quantum computer.

It quotes Pan Jianwei, lead scientist on the project, as saying, “(T)heir machine would eclipse all of the world’s supercomputers in carrying out the calculations” in a few years’ time.

Previously Pan did research in Austria but could not find a teaching job in the West in spite of his great achievement in quantum technology. China invited him back and provides more funds than he needs and has thus enabled to realize his dreams in building the largest quantum communication network on land, launching world first quantum communication satellite and developing world first quantum computer.

Chinese government is rich and grudges no funds for its talented scientists and engineers. No wonder China can catch up with and surpass the West so fast.

We must question why in the first place he had to look for a job in Austria; if he was employed what a loss it would be for China.

Also think how much we might have missed in the form of loss opportunities by losing out the talent.

Wow, so young and so many records already under his sleeve.

But, there is no such thing as being useless as long as one puts honest effort for the long term betterment and security of his/her nation.

Some are just at the forefront, so, the media notices them.

Every contribution, regardless of publicity, is meaningful. So many real heroes/patriots are nameless and will likely be never known.

West continues to be far far ahead of China in terms of scientific research, specially quality scientific research. Chinese scientists overwhelmingly favor Western Universities for both their PhD, post-Doc, and then faculty positions.

I follow the research in Nature and Science regularly, and China contributes less than 5% of the research articles in those journals (which are universally considered the most prestigious science journals).

In fact, Chinese researchers abroad, contribute more to these journals than Chinese researchers in China.

The top most Chinese talent still doesn't want to come to China yet.

Some notable exceptions are: Pan Jianwei, Lu Chaoyang, Yan Nieng

I never claimed India is in the quantum race yet.

However, it is you who keep claiming that somehow China is ahead of US in quantum computing, which is a totally inaccurate statement.

China is indeed ahead in quantum computer and virtually anything quantum. You use this bogus or bias western source to prove your point so it's invalid. Those report or assessment will purposely omit China lead and try to brag as much as possible abt western one.
 
.
It's not embarrassing at all to admit US leads RD in quantum computing although China made great progress in this field in past few years. Within 30 years, China together with US will lead innovation in science and technology, Europe and Japan probably decline, India will follow up.

How do you know?
In fact, judging by this statement of yours, you don't even seem to know much about quantum physics, or the research happening in the field.

Your remark regarding China leading in "anything quantum" is hilarious.

Quantum Physics is the dominant physical framework of understanding the world. Which means it is applied in EVERYTHING.

There is quantum thermodynamics, quantum chemistry; there is even an up and coming field called quantum biology.

We are talking here only about Quantum IT (Information Technology), which uses quantum principles for the evolution of the next generation of IT infrastructure superseding the classical one.

It would broadly include the following fields:
  1. Quantum Cryptography, and Quantum Communications: This is the field where China is strongest at, and is perhaps even leading. China's quantum satellite, and fibre optic link fall in this category.
  2. Quantum Sensors, and Hardware: This is the field where China produces good work, but US and EU is in the lead.
  3. Quantum Computing: This is where US leads by a margin.
  4. Theoretical Quantum Computing, Algorithms: China doesn't even feature here. China is good in experimental physics, not in theoretical one.

You use this bogus or bias western source to prove your point so it's invalid.

I have quoted Scott Aaronson, who is a leading theoretical quantum physicist. In fact, your sources are far more biased, and don't know anything about the stuff they are writing.

Pan Jianwei's team made what is called a Boson Sampling Machine. It is not a universal quantum computer. And it is not even being pursued by other research groups, who are going all in for a universal quantum computer.

Those report or assessment will purposely omit China lead and try to brag as much as possible abt western one.

In fact they do the opposite. They overplay China's advance in quantum computing so that they can lobby for funds. (Both in US and EU)

Now, Mr. @Beast please state your sources, and analysis on why do you think China leads quantum computing, and virtually "anything quantum."

As I know, US , China and Japan these three nations are indeed pouring tons of money into this latest technique revolution . West European nations were stuck into two many mess , and their government has not enough resource invested in the front fields .
It is far way from enough to develop all the advanced techs with the resource of University or academy today.

In 10 to 20 years, the gap of technology would emege, and West Europe would bend to US completely.

China Races to Show Quantum Advantage
By Tiffany Trader
May 3, 2017

Quantum computing has been one of those long-promised breakthroughs, forever on the horizon yet just out of reach, but a quickening is upon us with Google, IBM and others vying to cross a major threshold in a matter of months (as reported recently by MIT News). The target they are gunning for is quantum supremacy, the term coined by theoretical physicist John Preskill to define the point at which a quantum processor surpasses the ability of the largest classical supercomputer to carry out a well-defined problem.

A front-runner in the global supercomputing race, China is also proving itself as a world leader in quantum research. At a press conference in Shanghai on Wednesday, a quantum research team from Eastern China announced they had a hit a milestone in creating a quantum machine that can compete with today’s classical computers.

Team leader quantum physicist Pan Jianwei, an academician of the Chinese Academy of Sciences and his colleagues Lu Chaoyang and Zhu Xiaobo (of the University of Science and Technology of China), and Wang Haohua (of Zhejiang University) reported that their quantum processors could solve certain tasks faster than classical machines.

The researchers’ quantum device is called a boson sampling machine, considered “a strong candidate to demonstrate ‘quantum computational supremacy’ over classical computers,” according to the team. At the crux of the advance are two primary components: “robust multiphoton interferometers with 99% transmission rate and actively demultiplexed single-photon sources based on a quantum dot–micropillar with simultaneously high efficiency, purity and indistinguishability.”

The scientists’ implementations of three-, four- and five-photon boson sampling achieve sampling rates of 4.96 kHz, 151 Hz and 4 Hz, respectively, reaching speeds 24,000 times faster than previous experiments. “Our architecture can be scaled up for a larger number of photons and with higher sampling rates to compete with classical computers,” they write in their paper, which was published in the scientific journal Nature Photonics on Tuesday.

The Chinese team said their prototype quantum computing machine is 10 to 100 times faster than the first electronic computer, ENIAC, and the first transistor computer, TRADIC, and could “one day could outperform conventional computers.”

University of Texas at Austin Professor Scott Aaronson, who proposed the boson sampling machine, reported that the research showed “exciting experimental progress.”

“It’s a step towards boson sampling with say 30 photons or some number that’s large enough that no one will have to squint or argue about whether a quantum advantage has been attained,” he told the South China Morning Post.

Pan Jianwei is also the chief engineer of the world’s first quantum satellite, launched by China in August 2016. The goal of the project is to secure ultra-secure “hack-proof” quantum communications and to demonstrate features of quantum theories, such as entanglement. In January, Jianwei stated, “the overall performance has been much better than we expected; it will allow us to conduct all our planned experiments using the satellite ahead of schedule and even add some extra ones.”

RD is not a money only thing. US has an attractive atmosphere and mechanism which is the core competency of US. For most European countries, esp Eastern Europe, brain drain is a big issue, most talents either move to Germany, France, UK or US, this is a ramification of globalization. Esp. Along with the politically turning right and instability of European society, I reckon more and more European scientists would emigrate to US. The distribution of talents is polarizing globally.

For Japan, due to its stagnating economy, closed mindset and aging population, even if more money is poured into RD, the output is supposed to be insignificant in the future, any new promising startup or new industrial leader in past decade from Japan? Japan still dominate many sectors e.g. high precision parts, robotics, high end machine tool, automobile etc, I hope China will grab more and more shares from Japan and Korea from these industrial sectors.

I am talking about next generation tech .
You have no idea about what Japanese corp and Japan academy has achieved in terms of AI, Cloud , new material and green resource.
In some fields, Japan is even stronger than US.
Do not underestimate anyone .
Japan architecture of R$D has a lot of strongpoints derserving China learning.
The development of China doesn't depend on bragging.

I'm not underestimating Japan, Japan is still strong in many sectors as I mentioned. However the output is primarily based on talent flow, less and less Japanese pursue oversea STEM degree in US, meanwhile Japan is a very restrict country for immigrant. I'm predicating the trend. Did you ever see my bragging on PDF?
