观测量的量子纠错修正

Quantum Error Correction of Observables

Cedric Beny, Achim Kempf, David W. Kribs

摘要:

在[1]中,通过考虑量子动力学的海森堡图像,提出了一种基于算符代数的量子纠错的形式。由此产生的理论允许混合量子经典信息的校正,并且不需要编码状态完全处于相应的子空间或子系统之一中。在这里,我们对[1]的结果提供了详细的证明,导出了一些新的结果,并通过扩展讨论阐明了关键点。我们还提出了几个例子,并指出如何理论可以扩展到算子空间和一般的正算子值的措施。

英文摘要:

A formalism for quantum error correction based on operator algebras was introduced in [1] via consideration of the Heisenberg picture for quantum dynamics. The resulting theory allows for the correction of hybrid quantum-classical information and does not require an encoded state to be entirely in one of the corresponding subspaces or subsystems. Here, we provide detailed proofs for the results of [1], derive a number of new results, and we elucidate key points with expanded discussions. We also present several examples and indicate how the theory can be extended to operator spaces and general positive operator-valued measures.
