【摘要】 构造了辐射场的一类新的非经典态,即双模真空态与相干态的叠加态.并讨论了它的非经典性质,即压缩效应、亚泊松分布、两模间二阶相关函数.数值计算结果表明,双模真空态与相干态的叠加态具有非常显著的非经典性质,因此双模真空态与相干态的叠加态是一类新的非经典光场态.更多还原

【Abstract】 A new class of non-class of non-classical state of the radiation field is constructed,which is called superposed state of two-mode vacuum state and two-mode coherent state.The non-classical properties are discussed,which are squeezed effect,sub-Poissonian distribution and the second-order cross correlation function between the two modes.The numerical results show that the superposed state of two-mode vacuum state and two-mode coherent state possesses very obvious non-classical properties.Therefore it is a new non-classical quantum state.更多还原
