In this paper, we propose a novel scheme for quantum two-state sharing (QTSS) by using a five-qubit entangled state as the quantum channel. In this scheme, a dealer Alice has two unknown quantum states and wants her three agents to share the quantum states. After the dealer performs a four-qubit measurement on her qubits, and the controller employs a single-qubit measurement on his own qubit, the state receivers can reconstruct the original states by using the appropriate unitary operations. It is shown that, only if all agents collaborate with each other, the QTSS can be completed with unit success probability.

量子两态共享

在本文中，我们提出了一种新的量子双态共享 (QTSS) 方案，该方案使用五量子比特纠缠态作为量子通道。在这个方案中，经销商 Alice 有两个未知的量子态，并希望她的三个代理共享量子态。在经销商对她的量子位执行四量子位测量，并且控制器对他自己的量子位进行单量子位测量后，状态接收器可以通过使用适当的酉运算来重建原始状态。结果表明，只有所有智能体相互协作，QTSS 才能以单位成功概率完成。
