一种量子纠错方案的性质及存储错误阈值估计

Quality of a Quantum Error Correcting Scheme and Memory Error Threshold Estimation

Pedro J. Salas

摘要:

对Calderbank-Shor-Steane [[7,1,3]]量子码的纠错能力以及利用多个辅助态提取容错伴随式进行了数值研究。一个简单的概率表达式来表征代码的能力,纠正编码的量子比特已被认为是。该概率作为校正质量标准,允许比较不同恢复方案之间的纠错能力。存储器错误阈值的计算是通过那些被认为是最好的方法。

英文摘要:

The error correcting capabilities of the Calderbank-Shor-Steane [[7,1,3]] quantum code, together with a fault-tolerant syndrome extraction by means of several ancilla states, have been numerically studied. A simple probability expression to characterize the code ability for correcting an encoded qubit has been considered. This probability, as a correction quality criterion, permits the error correction capabilities among different recovery schemes to be compared. The memory error threshold is calculated by means of the best method of those considered.
