量子纠错中的关联误差

Correlated Errors in Quantum Error Corrections

W. Y. Hwang, D. Ahn, S. W. Hwang

摘要:

我们表明,错误不会产生相关的量子比特不直接相互作用(或耦合到)彼此。一般来说,除了正在执行双量子位门操作的情况之外,假设这种无量子位相互作用条件。特别地,在集体退相干模型中满足无量子比特相互作用条件。因此,在集体退相干中误差不相关。因此,我们可以说,目前纠正单量子比特错误的量子纠错码将在大多数情况下工作,包括集体退相干。

英文摘要:

We show that errors are not generated correlatedly provided that quantum bits do not directly interact with (or couple to) each other. Generally, this no-qubits-interaction condition is assumed except for the case where two-qubit gate operation is being performed. In particular, the no-qubits-interaction condition is satisfied in the collective decoherence models. Thus, errors are not correlated in the collective decoherence. Consequently, we can say that current quantum error correcting codes which correct single-qubit-errors will work in most cases including the collective decoherence.
