非纯量子码的量子Hamming界问题的研究进展
Progress on Problem about Quantum Hamming Bound for Impure Quantum Codes
摘要:
量子纠错码理论中一个著名的开放问题是,不纯量子码的参数是否可以违反纯量子码的量子汉明限。我们部分解决了这个问题。我们证明了存在一个阈值,使得任意量子码在任何时候都必须服从量子汉明限。我们列出了小d和二进制量子码的一些值。
英文摘要:
A famous open problem in the theory of quantum error-correcting codes is whether or not the parameters of an impure quantum code can violate the quantum Hamming bound for pure quantum codes. We partially solve this problem. We demonstrate that there exists a threshold such that an arbitrary quantum code must obey the quantum Hamming bound whenever . We list some values of for small d and binary quantum codes.
