通过操纵受激参量下转换的状态，在不应用后选择的情况下产生多光子路径纠缠。对两个输出空间模式之一的特定测量导致另一模式的光子的非局域聚束，形成所需的多光子路径纠缠态。我们目前的情况下，预示着双光子路径纠缠态的实验结果，并展示了如何将这一计划扩展到更高的光子数。
Multiphoton path entanglement is created without applying postselection, by manipulating the state of stimulated parametric down-conversion. A specific measurement on one of the two output spatial modes leads to the nonlocal bunching of the photons of the other mode, forming the desired multiphoton path entangled state. We present experimental results for the case of a heralded two-photon path entangled state and show how to extend this scheme to higher photon numbers.
