Quantum computation

Differences with classical computation

In classical computation there is the concept of a discrete bit, taking only one of two values. However , the world which classical physics describes is that of continua. Thus this is obviously not an ideal way of attempting to describe or simulate the world in which we live. Feynman was the first to consider the idea of a quantum computer being necessary to simulate the quantum mechanical world in which we live.
