Quantum computer

Quantum computers are one of the most common types of computers in the Galaxy.

The basis for data in a quantum computer is a qubit, which unlike the bit in a binary machine which encodes either a one or a zero, encodes both possible states at the same time, a quantum superposition of 0 and 1. Thereby not only reducing the time needed for processing complex mathematical equations, such as the factoring of very large numbers, by at least three orders of magnitude; this is done by directly manipulating the probability amplitudes at the gate level.

It also permits the modelling of quantum systems in real time, thereby making it invaluable in the design of nanotech. All quantum computers are required to be built using reversible logic (unitary transforms).
