英语词汇“quantum bit”的英英意思、用法、释义、翻译、读音、例句、短语、词组-英语词典

quantum bit n. (in a quantum computer) a physical system for storing information that is capable of existing in either of two quantum states or in a superposition of both (e.g. a spinning particle), and hence can represent two different binary values simultaneously; a unit of information held in this way; also called qubit.

Vanstone Adv. in Cryptology 49 The first quantum bit commitment scheme ever proposed is due to Bennet and Brassard..(actually, the protocol they describe is only claimed to implement coin tossing, but it is obvious how to modify it in order to implement bit commitment).

1994 Computing 28 July 38/6 To take advantage of any increase in information capacity, the messages would be encoded in particles in a range of quantum states, each having independent probabilities. These quantum bits—‘qubits’—should allow an increase in data compression in certain coding regimes.
