| 摘 要： | 压缩相干态是准粒子空间的相干态,研究大振幅情况下的单模压缩相干态腔场,其特性类似于大振幅下的单模相干态腔场,与自旋1/2的两态粒子同构.文中提出一种方案,利用大失谐的JaynesCummings模型来制备处于压缩相干态的三个腔场的类自旋GreenbergerHorneZeilinger(GHZ)态.

| Abstract: | Squeezed coherent states are coherent states in quasi——particle space. We note that the characteristic of the single mode cavity field in a squeezed coherent state with sufficiently large amplitude is analogous to that of the single mode cavity field in a coherent state and is isomorphic to a two-state particle with spin-1/2. A scheme is presented to prepare spin-type Greenberger-Horne-Zeilinger(GHZ)states of three cavities in squeezed coherent states via the Jaynes-Cummings model with large detuning. |
