In this work, we analyze the concept of quantum bridge using Non-Maximally Entangled (NME) states. We propose two schemes for the quantum teleportation of an unknown qubit using an NME channel as a bridge between the sender and the receiver. We show that quantum channels and the measurements are equivalent in achieving the quantum teleportation only when the degree of entanglement is the maximum.

量子隐形传态中通道纠缠与测量的等效性

在这项工作中，我们使用非最大纠缠 (NME) 状态分析了量子桥的概念。我们提出了两种使用 NME 通道作为发送者和接收者之间桥梁的未知量子比特的量子隐形传态方案。我们表明，仅当纠缠度最大时，量子通道和测量在实现量子隐形传态方面是等效的。
