利用非对称多体纠缠态作为量子通道的密集编码方案

Dense Coding Plan of Using a Non--symmetric Multipartite Quantum Channel

针对非对称两粒子纠缠态作为量子通道的密集编码方案，提出了一个利用非对称多粒子纠缠态作为量子通道的方案．该方案通过理论推导的方法，把两体态推广到多体态，即发送者（Alice）和接收者（Bob）利用共享的N对处于非对称希尔伯特空间的粒子来进行编码．研究结果表明，信息传输效率得到大大提高．

A dense coding scheme which employs non--symmetric two--particle entangled state as quantum channel is advanced. By way of theoretical deduction, the two--particle state is extended to multipartite state： namely, the sender （Alice） and the receiver （Bob） carry along coding by making use of the shared N particle beams in non--symmetric Hilbert space. As a result, the efficiency of information transmission is dramatically increased.
