摘要 采用J-C模型,在原子与场共振相互作用时,就半经典和全量子化两种情形下推导出量子光学中一个十分有用的幺正时间演化算符,并应用这一算符展示了一种量子隐形态传输的方案. Adopts J-C modle, when the atom and field resonance interact, to derive a useful unitary time-evolution opeartor under the situation of semiclassical and full quantum, amd applies the operator to show a scheme of communication of unknown quatum state.
