Quantum computing, quantum computer is a physical device that follows the laws of quantum mechanics and processes information based on the above principles. Compared with classical computing, quantum computing has two main characteristics: stronger parallel computing ability and lower energy consumption.

Quantum communication, quantum computing is a computing technology that uses quantum bits as the basic unit and realizes data storage through the controlled evolution of quantum States. It has enormous information carrying capacity and super parallel processing ability that classical computing can't match.

3. Quantum chip is the physical realization and hardware system of quantum computer. Quantum algorithm is to control and use a universal quantum computer conveniently, and the programming language of quantum computer is used as a medium to transmit information between people and quantum computers.

4. The existing quantum algorithms are generally solidified in special quantum computing equipment. Although the principle verification of various physical implementations of quantum computing has developed rapidly, it is internationally recognized that quantum general-purpose computers cannot be realized in a short time.
