摘 要:
量子信道为最大纠缠态的密集编码方案中,编码操作可以分为翻转操作和相位操作.存在相位编码操作是实现密集编码的关键,构造了量子信道为三能级部分纠缠态的相位密集编码算符,并给出了存在相位编码的条件.[著者文摘]

Abstract:
In the protocol of quantum dense coding by a maximally entangled state, the encoding operators are divided into two classes： the rotation operators and the shift operators. The latter is the key for quantum dense coding. The condition for shift encoding in the case of three-level non-maximally entangled state between two parties is proposed and the expression of the shift operators is also presented.[著者文摘]
