IT 104 Quantum Computation
Quantum Computation Information in classical computation is encoded in bits; bits are digitally represented by 1s and 0s, and physically represented by electric gateways that open or close known as transistors. At the atomic scale, these gateways fail, as electrons bypass closed transistors through the process of quantum tunneling. Quantum computation overcomes this limitation and utilizes quantum mechanics to increase computation speed. In quantum computation, qubits replace bits and transistors are replaced by polarized photons. Qubits exponentially increase computation speed by a factor of two per qubit, due to superpositoning and quantum entanglement. Superpositioning allows photons to hold both states, 1 and 0, concurrently until measured, this means multiple algorithms may be computed simultaneously. Quantum entanglement "links" photons together in such a way that information about all "linked" photons may be known by observing one. Impact of Quantum ...
