我们提出了一种从两个脉冲II型光学参量振荡器中有条件地产生路径纠缠垂直条N，0 >+垂直条0，N >态的测量方案。我们计算了产生态的保真度和协议的成功概率。触发检测器被假定为具有有限的死区时间，并且对于短脉冲触发场，它们被建模为具有有限效率的开-关检测器。连续波操作的参量振荡器也被认为是。
We propose a measurement protocol to generate path-entangled vertical bar N,0 >+vertical bar 0,N > states conditionally from two pulsed type II optical parametric oscillators. We calculate the fidelity of the produced states and the success probability of the protocol. The trigger detectors are assumed to have finite dead time, and for short pulse trigger fields they are modeled as on-off detectors with finite efficiency. Continuous-wave operation of the parametric oscillators is also considered.
