# Quantum Computer

Computer uses the sets of 0 and 1 for calculation.
And use the nature of electricity for this function.

Quantum has not only the nature like 0 and 1 but also overlay and tunnel effect.

Quantum Computer uses the nature of quantum to improve speed of the calculation.

##
Use of Overlay

General computer serchs the best combination of 0 and 1 from specific combination of 0 and 1.

Quantum Computer starts same serch from ambiguous state.

##
Use of Tunnel Effect

General computer cannnot understand the difference local minimum and minimum when one of the local mimimum is serched.

Quantum computer can serch mimimum.

##
Difference to Use the Concept of Probability

General computer uses the concept of probability with the combination of 0 and 1.
So ambiguity of probability is made complexity and large amount of the combination.

Quantum computer uses quantum.
And quantum itself has the nature of probability.
