Quantum Dense Coding Using Three-level Partly Entangled State
摘要/Abstract
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。
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.
