我们在实验上制备并表征了一个六光子偏振纠缠态，通常称为“Psi（+）（6 π）”.这是实现与三重发射纠缠光子对从一个单一的源，它不使用任何干涉重叠的过滤程序。该装置是非常稳定的，我们观察到的六光子态与高保真度。所观察到的状态可以用于远程克隆和秘密共享协议的演示。
We experimentally generate and characterize a six-photon polarization entangled state, which is usually called `Psi(+)(6)'. This is realized with a filtering procedure of triple emissions of entangled photon pairs from a single source, which does not use any interferometric overlaps. The setup is very stable and we observe the six-photon state with high fidelity. The observed state can be used for demonstrations of telecloning and secret sharing protocols.
