多模条件光门的准概率方法

Quasiprobability methods for multimode conditional optical gates

G. J. Milburn

摘要:

我们提出了一种方法计算的行动条件的线性光学变换,条件光子计数,为任意的信号状态。该方法是基于Q-函数,一个反正常序矩的准概率分布。我们处理任意数量的信号和辅助模式。在任意乘积数状态下准备辅助模式。我们构造的条件,非幺正,信号变换为任意光子数计数的每一个辅助模式。

英文摘要:

We present a method for computing the action of conditional linear optical transformations, conditioned on photon counting, for arbitrary signal states. The method is based on the Q-function, a quasi probability distribution for anti normally ordered moments. We treat an arbitrary number of signal and ancilla modes. The ancilla modes are prepared in an arbitrary product number state. We construct the conditional, non unitary, signal transformations for an arbitrary photon number count on each of the ancilla modes.
