Quantum computing
Quantum computing Quantum computing is the use of quantum-mechanical phenomena such as superposition and entanglement to perform computation . A quantum computer is used to perform such computation, which can be implemented theoretically or physically. [1] :I-5 The field of quantum computing is actually a sub-field of quantum information science , which includes quantum cryptography and quantum communication . Quantum Computing was started in the early 1980s when Richard Feynman and Yuri Manin expressed the idea that a quantum computer had the potential to simulate things that a classical computer could not. [2] [3] In 1994, Peter Shor shocked the world with an algorithm that had the potential to decrypt all secured communications. [4] There are two main approaches to physically implementing a quantum computer currently...
