摘要
信息在传输过程中,经常会受到噪声的影响。为了避免噪声的影响,就需要对量子信息进行纠错。量子纠错定理描述量子信道可纠错的充分必要条件。但目前的纠错定理基于有限维量子系统给出。本文研究无限维量子纠错定理,给出量子信道具有有限维纠错码的充要条件。
Information is often affected by noise during transmission. In order to avoid the effect of noise,it is needed to correct the quantum information. The current quantum error-correc- tion theory gives the sufficient and necessary conditions for the error-correction of quantum chan- nel in finite dimensional quantum systems. In this paper, the quantum error-correction theory in infinite dimensional quantum systems was studied, and the necessary and sufficient conditions were given for the error-correction of quantum channel with finite dimensional error correcting codes.
