我们表明，内部损耗和存活条件可以在无源线性光学电路中激活反常广义聚束。我们引入了一个条件聚束概率，即在所有光子存活的情况下，所有光子占据可访问输出模式的目标区域。对于双光子输入，我们证明对于任何电路尺寸和损耗配置，该概率总是单调的，尽管多模目标区域可以反转单调方向。对于最小的三模有损干涉仪中的三光子输入，我们发现了一种非单调异常，其中对于部分可区分的光子，条件聚束概率最大。这种行为对于相应的无条件目标区域概率是被禁止的，表明存活条件损耗改变了广义聚束的最小层次结构。
英文摘要
We show that internal loss and survival conditioning can activate anomalous generalized bunching in passive linear optical circuits. We introduce a conditional bunching probability that all photons occupy a target region of accessible output modes, given that all photons survive. For two-photon inputs, we prove that this probability is always monotonic for any circuit size and loss configuration, although a multimode target region can reverse the monotonic direction. For three-photon inputs in a minimal three-mode lossy interferometer, we find a nonmonotonic anomaly in which the conditional bunching probability is maximized for partially distinguishable photons. This behavior is forbidden for the corresponding unconditioned target-region probability, demonstrating that survival-conditioned loss changes the minimal hierarchy of generalized bunching.
