This prototype quantum computer system uses superconducting qubits and microwave control technology to achieve basic quantum operations such as controlled quantum entanglement, superposition and quantum gate operation. At the same time, the system also has the implementation ability of quantum random walk algorithm, which is a typical application of quantum computing, to solve graph theory and optimization problems.

The emergence of this prototype quantum computer system marks that China's research level in the field of quantum computing has reached the international leading level. It has scalability and is expected to be applied to quantum simulation, quantum chemistry, quantum cryptography and noise reduction in the future, and has a wide range of application prospects.
In the first half of 2017, Chinese scientists released the world's first optical quantum computer that surpassed earlier traditional computers, achieving entanglement of 10 superconducting qubits and leading the world in manipulation quality. At the end of 2017, IBM announced the launch of the world's first 50-qubit quantum computing prototype.
