摘要

我们通过实验证明了一种简单的产生四光子簇态的方案。我们证明了产生态具有真正的四量子比特纠缠，它与包括GHZ和W类型的纠缠区分开来。

Simple experimental generation of a four-photon cluster state and distinguishing classes of genuine four-qubit entanglement using witness operators

We experimentally demonstrate a simple scheme for generating a four-photon cluster state. We show that the produced state has genuine four-qubit entanglement which is discriminated from a class including GHZ and W types of entanglement.
