Noun
(quantum mechanics) Loss of quantum coherence (phase relation between the quantum states of particles) in a physical system as it interacts with its environment.
(engineering, dated) The normal condition of sensitiveness in a coherer; reversion to such condition.
Source: en.wiktionary.orgIf the error rate is small enough, it is thought to be possible to use quantum error correction, which corrects errors due to decoherence, thereby allowing the total calculation time to be longer than the decoherence time. Source: Internet
If a quantum computer with a sufficient number of qubits could operate without succumbing to noise and other quantum decoherence phenomena, Shor's algorithm could be used to break public-key cryptography schemes such as the widely used RSA scheme. Source: Internet
Neither the excitation of the single ion (which is a degree of freedom of the proposed system) leads to decoherence, something which is proven by Welcher Weg detectors which can excite atoms without momentum transfer (which causes the loss of coherence). Source: Internet
" citation A 2005 poll of fewer than 40 students and researchers taken after a course on the Interpretation of Quantum Mechanics at the Institute for Quantum Computing University of Waterloo found "Many Worlds (and decoherence)" to be the least favored. Source: Internet
Error rates are typically proportional to the ratio of operating time to decoherence time, hence any operation must be completed much more quickly than the decoherence time. Source: Internet
Many-worlds did just fine, garnering support on a level comparable to, but somewhat below, Copenhagen and decoherence." Source: Internet
