China plans to create 20-cubanow quantum system this year
Source:More and more companies are now entering in the race to create quantum computers. Recently, we reported that Google started to create . And now came the news from China: a group of researchers from the Chinese University of Science and technology and Zhejiang University based on the available 10-cubitas quantum system plans by the end of 2017 to increase the number of qubits in it 2 times.
Chinese quantum system based on the use of single photons, very cold atoms and superconducting electronic circuits. Despite a bold request for extension to 20 qubits, scientists make predictions about what next year's system will be able to count up to 30 qubits. In 2016, the researchers were able to create a source of single photons based on semiconductor quantum dots. Now this source supplies photons electrically programmable elements of photonic circuits that make up a quantum computer.
At the moment 10-Cubana quantum computing, the system shows a performance level of 24 000 times the speed of operation of the variant of a quantum system with five photonic qubits. This is considering the fact that 5-cubita system showed a very high level of performance. As stated by researchers,
«Our architecture quantum computing system allows the extension to any number of photons. At the same time, increasing the number of photons the performance of the system will grow exponentially. Us plan for next year 30-Cubana quantum system has to be able to compete with the most powerful «common» computers».
