To achieve practical use of the quantum computer in physics, we need to organically integrate universal quantum logic gates, to keep quantum entanglement between qubits, and to be able to manipulate them. With the increase in the number N of integration of qubits, the loss of quantum coherence...

过去40年里,量子计算机慢慢从理论学家画在黑板上的潦草曲线发展到大学实验室里的小机器,再演变成世界上一些最大公司的研究项目。 Now one of those machines, built by researchers at Google, has at last shown what all the fuss is about. It appears to have performed, in just over three minutes, a ...
In a 2019 report, the National Academy of Sciences said thata practical quantum computer is a decade away. Google's quantum optimism Google believes it's on the right track, though, and that quantum progress will outstrip classical progress. It looks forward not merely to exponential performance...
the researchers estimate, the world’s most powerful classical supercomputer would take around 10,000 years to complete. Google’s machine is a special-purpose device that was designed to solve a contrived problem with few practical uses. But this display of so-called “quantum supremacy” is no...
This article explains the principles of quantum computing, how it compares to classical computing, and how it uses the principles of quantum mechanics. History of quantum computing The idea of a quantum computer was born out of the difficulty of simulating quantum systems on a classical computer....
China has installed its first serialquantum computerthat can be used to solve practical problems. This was announced at the end of January 2023 by the newspaper of the Ministry of Science of thePRC. Read morehere. 2022 China bypasses the United States in the number of patents on quantum tech...

To run a quantum computer, we need to manipulate individual qubits and perform entangling operations on pairs of qubits. Once we can perform such single-qubit and two-qubit “quantum gates” with sufficient accuracy, and measure and initialize the qubits as well, then in principle we can perfor...
The teams says that the computer’s performance matches that of existing state-of-the-art systems and believe that their setup could bring the widespread use of practical quantum computers a step closer to reality. As technology improves, quantum computers are integrating increasing numbers of qubits...
