China has built the world’s first ever Quantum computer

Chinese scientists have successfully built the world’s first quantum computing machine which that is 24,000 times faster, due to this, it’s going to dominate existing supercomputers we have in the world.The scientists announced this great achievement at a press conference at the Shanghai Institute for Advanced Studies of University of Science and Technology of China.

Recently, Pan Jianwei of the Chinese Academy of Sciences, Lu Chaoyang and Zhu Xiaobo of the University of Science and Technology of China and Wang Haohua of Zhejiang University set international records in quantum control of the maximal numbers of entangled photonic quantum bits and entangled superconducting quantum bits.This advancement means that we are going to get computers which performs 100,000 faster than computers of today.

Just recently, Chinese leading 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 — set two international records in quantum control of the maximal numbers of entangled photonic quantum bits and entangled superconducting quantum bits.

Pan said quantum computers could, in principle, solve certain problems faster than classical computers. Despite substantial progress in the past two decades, building quantum machines that can actually outperform classical computers in some specific tasks — an important milestone termed “quantum supremacy” — remains challenging.

What is quantum computing?

Quantum computing takes advantage of the strange ability of subatomic particles to exist in more than one state at any time. Due to the way the tiniest of particles behave, operations can be done much more quickly and use less energy than classical computers.

In classical computing, a bit is a single piece of information that can exist in two states – 1 or 0. Quantum computing uses quantum bits, or ‘qubits’ instead. These are quantum systems with two states. However, unlike a usual bit, they can store much more information than just 1 or 0, because they can exist in any superposition of these values.

Across the world a lot of researches are going on,Last year, a team of Google and Nasa scientists found a D-wave quantum computer was 100 million times faster than a conventional computer. But moving quantum computing to an industrial scale is difficult.IBM recently announced its Q division is developing quantum computers that can be sold commercially within the coming years.

Commercial quantum computer systems “with ~50 qubits” will be created “in the next few years,” IBM claims. While researchers at Google, in Nature comment piece, say companies could start to make returns on elements of quantum computer technology within the next five years.Last year, Pan and Lu Chaoyang developed the world’s best single photon source based on semiconductor quantum dots.

Now, they are using the high-performance single photon source and electronically programmable photonic circuit to build a multi-photon quantum computing prototype to run the Boson sampling task.The test results show the sampling rate of this prototype is at least 24,000 times faster than international counterparts, according to Pan’s team.

At the same time, the prototype quantum computing machine is 10 to 100 times faster than the first electronic computer, ENIAC, and the first transistor computer, TRADIC, in running the classical algorithm, Pan said.
