# Quantum computer

### From Conservapedia

Quantum Computers are a specialized field of computing, utilizing the innate ability of subatomic particles to be 1 and 0 simultaneously.^{[1]} It differs from the traditional Turing Computer because while normal computers can only be 1 or zero at a given point, Quantum Computers can be anything from 0-1 at the same time. A good analogy is a tape of unlimited length that is divided into little squares. Each square can either hold a symbol (1 or 0) or be left blank. A read-write device reads these symbols and blanks, which gives the machine its instructions to perform a certain program. The quantum computer would be the tape exists in a quantum state, as does the read-write head. This means that the symbols on the tape can be either 0 or 1 or a superposition of 0 and 1; in other words the symbols are both 0 and 1 (and all points in between) at the same time. While a normal Turing machine can only perform one calculation at a time, a quantum Turing machine can perform many calculations at once.^{[2]}
