on April 10, China tourism association of six secondary board and BBS transformation and upgrading of the tourism industry development in hebei langfang.On the BBS, academician of Chinese academy of sciences dean bai frontier science and technology development of China "application" the theme of the report.After the meeting, bai in an interview with reporters, according to the Chinese academy of sciences are developing China's first quantum computer, is expected in the last few years is expected to be developed.
in recent years, the traditional computer development has gradually encountered walls, communications, power consumption and so on a series of problems, the performance of the traditional computer growth is more and more difficult.Therefore, to explore new physical principle, the demand for high performance computing technology was born.
a quantum computer is a kind of follow the rules of quantum mechanics, high-speed computing, storage and processing of quantum information of physical device, its operation is quantum algorithms, processing speed, billions of times faster than conventional computers.For example, use one hundred million times of "tianhe ii super computer (computing power is the most powerful supercomputers Titan twice) equations for solving a 0.1 billion variable, the time required for the 100;While the use of a quantum computer to solve the same equations of one trillion times, just 0.01 seconds.Therefore, quantum computing in nuclear simulation, code, material and micro-nano manufacturing and other fields have prominent advantages, is a new concept recognized the development trend of high performance computing field.
at the end of last year, Google said developed quantum chip, and using the chip of quantum computer D - Wave to solving a problem out one hundred million times faster than any other computer.Google's quantum chip USES the low temperature superconducting technology, superconducting system can be integrated, can integrate more qubits, but operation precision is far less than the requirement of quantum computing.Google D - Wave, therefore, is not a true quantum computer, quantum back the lighter, but only for a particular link, do a special computer algorithm, but is not a universal.
, by contrast, USTC quantum laboratory quantum chip is based on quantum dot system, although there will be less integration of quantum bit, but with better accuracy of quantum logic gates, in terms of building standard quantum computer, quantum laboratory USTC apparently chose the right path.
this year on March 3, Google quantum AI lab three scientists in a paper published in the journal nature, small quantum computing opportunities emerging in five years.According to the bai academician of the disclosed information, the Chinese may be ahead of the United States developed the first quantum computer.
