What's the difference between quantum computer and traditional computer?

When dealing with specific problems, quantum computer has the ability advantage far beyond the classical computer, because it has the ability of parallel computing.

Quantum computer is a very high-tech physical equipment. The core principle of this physical device is to follow the laws of quantum mechanics to perform high-speed mathematical and logical operations, and to store and process quantum information.

The characteristics of quantum computer mainly include strong information processing ability, fast running speed and wide application range. Compared with ordinary computers, quantum computers have natural advantages in some specific problems and can greatly shorten the running time. In the future, it will be widely used in artificial intelligence, Internet of Things and other fields.
