摘　　要：为克服长距离量子隐形传态方案中局域操作受限,且易受环境干扰影响通信质量的缺陷,利用1个三维Bell态和1个处于基态的辅助粒子作为量子信道,提出一个任意未知三维二粒子态的短距离量子隐形传态新方案.在该方案中,发送方和接收方除共享三维Bell态外,还必须预先共享1个辅助粒子.发送者对辅助粒子执行量子门运算后,需对其Bell粒子和未知量子系统进行联合测量,并向接收者发送该测量的经典信息.结果表明,接收者以100%的概率将自己拥有的Bell粒子与辅助粒子的量子态转换成被发送者摧毁的未知量子态的精确复制品.本方案传输距离短、承载信息量大、耗费纠缠资源少,在诸如芯片的固态器件上的量子隐形传态有很好的应用前景.A new scheme for short-distance quantum teleportation of an arbitrary unknown three-dimensional two-qutrit state is proposed,utilizing a three-dimensional Bell-state and a ground-state auxiliary qutrit as quantum channel.In this scheme,both the sender and receiver are required to pre-share an auxiliary qutrit in addition to sharing the three-dimensional Bell state.The sender performs joint measurements on their Bell qutrit and the unknown quantum system after performing quantum gate operations on the auxiliary qutrit,and sends the classical information of the measurement results to the receiver.Based on the measurement results,the receiver converts,with 100%probability,the quantum state of his/her own Bell qutrit and auxiliary qutrit into an exact replica of the unknown quantum state initially altered by the sender.This scheme exhibits advantages such as a short transmission distance,high information capacity,reduced consumption of entanglement resources,and promising applications in quantum teleportation for solid-state devices,such as on-chip implementations.
