Conventional computers use electric currents and its circuitry, and consist of many parts such as the CPU.

On the other hand, the quantum computers only uses electrons.

An electron has a spin, which can be a right or left rotation.

QThe argument can be made that quantum annealing can be said oneis a kind of quantum computer.

It is useful for solving particular problems like a combinatorial optimization problem.

The most famous one is the t"Traveling sSalesman" problem.

The computational complexity is very high, so it needs thousands of years using normal computersit takes normal computers thousands of years to solve it, but quantum annealing can solve the problem shortquickly.

Actually, a Canadian company, D-Wave Systems, has made this technology practicable, and Google is developing quantum computers.

It may occur aA technological revolution may occur.

Conventional computers use electric current and itsto function and their circuit, and consists of many parts such as a CPU.

On the other hand, the quantum computer uses electrons (to function).

QIt can be said that quantum annealing can be said oneis a kind of quantum computer.

Since quantum annealing is more of a technique perhaps it would be more correct to write "a kind of quantum computation" there.

Actually, a Canadian company, D-Wave Systems, has made this practicable, and Google is already developing quantum computers.
