How much better is the computing power of quantum computer than that of traditional equipment?

It is equal to an evolution, which is equivalent to completing the parallel processing of 2 n-power data. This is the advantage of quantum computer over classical computer. Quantum computer has the ability of ultra-parallel computing, which greatly surpasses the classical computer.

It provides a basis for quantum parallel computing. For example, in a traditional computer, four digits can represent 16 combinations, but you can only choose one of them. In a quantum computer, you can think that these 16 states exist at the same time, that is, an n-bit quantum computer =2, and an n-bit traditional computer performs calculation.

It will take about10.5 million years. However, if a quantum computer can be built, the calculation frequency is trillions of times, and it only takes 1 second to complete. From this perspective, the quantum parallel computing capability is very powerful.

If traditional computers are compared to bicycles, quantum computers are like airplanes. It takes 100 years to solve a system of equations with one billion variables by using a billion times "Tianhe II" supercomputer.

The computing power of a quantum computer is related to the number of quanta it can control. Experts predict that superconducting quantum manipulation can achieve 100 particles in ten years, which means that the computing power of this quantum computer can reach 100 times of the sum of all computing powers in the world at present.

If a device processes and calculates quantum information and runs quantum algorithms, it is a quantum computer. The general digital computer runs in the binary system of 0 and 1, which is called bit. But the function of quantum computer is far more powerful than it.
