The world's first quantum computer to go beyond the early classic computers

Enniac as the world's first classic algorithm computer, opened up an era belonging to the computer. Now, this classic computer age is ushering in a real challenge. Recently, two major breakthroughs have been made in quantum computer research based on photonic and superconducting systems by the Chinese University of Science and Technology Pan Jianwei, Lu Chaoyang, Zhu Xiaobo and other research groups affiliated with Zhejiang University Wang Haohua. Arrival to lay a solid technical foundation. Today, they announced in Shanghai that the world's first quantum computer surpassed earlier classic computers. In optical systems, the research team achieved the highest level of 10-photon entanglement in 2016 in the world. This year, on this basis, the world's first single-photon quantum computer capable of surpassing the early classical computers was built using the high-quality quantum dot single photon source developed independently in our country. Recent experimental tests show that the "Bose Sampling" speed of the prototype is at least 24,000 times faster than all similar experiments previously performed by international counterparts than the first ENHAC and TRADIC computer in human history Fast 10-100 times. In the past, quantum computing was faster than classical computers and remained in theory. The prototype took a solid first step towards turning this theory into reality, pushing quantum computers into the realm of competition with classic computers. This is the first time in history to transcend the early classical computer quantum simulator, which laid a solid foundation for the ultimate realization of the quantum computing beyond the classical computing power that the international academic community called "quantum domination." In the superconducting system, the research team independently developed a sample of 10-bit superconducting quantum wire. Through the high-precision pulse control and global entanglement operation, successfully achieved the multi-body pure entanglement of the largest number of superconducting quantum bits in the world and passed The tomographic method completely characterizes the 10-bit quantum state. This achievement broke through the record of nine quantum bit manipulations maintained by the United States and formed a complete system of superconducting computers, so that China has also entered the world first-class level in quantum computer research of superconducting systems. According to the plan, Pan Jianwei's research team will plan to have around 20 photon-quantum manipulations by the end of this year, design, preparation and testing of 20 superconducting qubits samples, and quantum computers will grow exponentially. >>> link Quantum computer refers to the use of quantum coherent superposition principle, in theory, with ultra-fast parallel computing and simulation capabilities of the computer. With the increase of manipulable particles, the computational power of quantum computers grows exponentially, which can provide an effective solution to large-scale computational problems that can not be solved by classical computers and has great potential for development. A quantum computer that manipulates 50 microscopic particles can even handle some specific problems even more powerful than supercomputers. If the speed of a classic computer is now a bicycle, the speed of a quantum computer is like an airplane. Parallel computing allows the quantum computer to complete a few years of supercomputer computing tasks in a matter of seconds and can solve the problem that traditional computers take millions of years to process in a matter of days. It is precisely because of its broad development prospects, many European and American developed countries and large high-tech companies have layout related research. At present, the key to the development of this technology lies in how to realize the coherent manipulation of large-scale quantum bits by developing high-precision and high-efficiency quantum state preparation and interaction control technologies. International academic research on quantum computing technology is mainly based on three systems of photons, super-cold atoms and superconducting circuits. The breakthrough made by Chinese scientists on photon and superconducting lines a few days ago has symbolic significance for the research and application of quantum computers.
