This is the first quantum computer that surpasses a conventional one

This May 3, at a press conference at the Shanghai Institute for Advanced Studies of the University of Science and Technology of China, the development of a quantum computer that was presented outperforms a conventional computer.

The finding puts us on the path of building future quantum computers thousands of times more powerful than today.

The Chinese quantum computer

A quantum computer with 50 quantum bits (qbits) would be more powerful in solving quantum sampling problems than today's fastest supercomputer. Y Jianwei bread, an academic of the Chinese Academy of Sciences, has managed together with his team of collaborators to conceive a photonic system with the first 5, 6, 8 and 10 intertwined photons in the world.

The team independently developed a superconducting quantum circuit that contained 10 superconducting quantum bits and entangled the 10 quantum bits through a global quantum operation.

The test results, published in Nature Photonics, show that the sampling rate of this prototype It is at least 24,000 times faster than international counterparts.

Quantum computing exploits the fundamental quantum overlay principle to allow ultra-fast parallel calculation and simulation capabilities. In normal silicon computer chips, the data is represented in one of two states: 0 or 1.

However, in quantum computers, data could exist in both states simultaneously, exponentially maintaining more information.

Chinese scientists intend to perform the manipulation of 20 intertwined photons by the end of this year, and will attempt to design and manipulate 20 superconducting quantum bits. And this is only the beginning, because Google is also carrying out its own achievements. The last great news we have lived in this field has come from IBM. This company has announced that before the end of 2017 it will have a quantum cloud computing service.
