摘　　要：为了利用少量资源制备多自由度杂化纠缠的W态,提出一种新的制备方案.采用不同实验器件设计了新的光路,并提出如何间接探测和验证所制备的杂化纠缠W态的实验方案.该方案光路设计简单,态制备的效率更高.In order to use a small amount of resources to prepare multi-degree-of-freedom hybrid entangled W state,this paper proposes a new preparation scheme.The article uses different experimental devices to design a new optical path,and provides an experimental scheme about how to indirectly detect and verify the prepared hybrid entangled W state.The optical path design of this scheme is simple,and the efficiency of state preparation is higher.

关 键 词：量子纠缠 多自由度 W态 光路
