利用简并量子码纯化GHZ态
Purifying GHZ States Using Degenerate Quantum Codes
摘要：
简并量子码是不显示完全错误伴随式的码。它们隐藏完整错误伴随式的能力使它们在某些量子信息处理任务中成为强大的资源。特别是，最容错的方法来纯化去极化贝尔态使用单向通信已知的日期涉及退化量子码。在这里，我们研究了三个密切相关的纯化方案之间共享的$m \geq 3$球员通过简并量子码和单向经典通信的去极化GHZ态。我们发现，我们的计划容忍更多的噪音比所有其他的单向方案已知的日期，进一步证明了退化量子码在量子信息处理的有效性。
英文摘要：
Degenerate quantum codes are codes that do not reveal the complete error syndrome. Their ability to conceal the complete error syndrome makes them powerful resources in certain quantum information processing tasks. In particular, the most error-tolerant way to purify depolarized Bell states using one-way communication known to date involves degenerate quantum codes. Here we study three closely related purification schemes for depolarized GHZ states shared among $m \geq 3$ players by means of degenerate quantum codes and one-way classical communications. We find that our schemes tolerate more noise than all other one-way schemes known to date, further demonstrating the effectiveness of degenerate quantum codes in quantum information processing.
