我们证明了算子量子纠错理论可以很自然地推广，因为它不仅允许对状态的约束，而且允许对可观测值的约束。由此产生的理论描述了可观测代数的校正（因此可以适当地称为“算子代数量子误差校正”）。特别地，该方法为量子-经典混合信息的校正提供了一个框架，并且它不要求状态完全处于相应的子空间或子系统之一。我们讨论了在量子隐形传态和量子相互作用中信息流研究中的应用。
We show that the theory of operator quantum error correction can be naturally generalized by allowing constraints not only on states but also on observables. The resulting theory describes the correction of algebras of observables (and may therefore suitably be called "operator algebra quantum error correction"). In particular, the approach provides a framework for the correction of hybrid quantum-classical information and it does not require the state to be entirely in one of the corresponding subspaces or subsystems. We discuss applications to quantum teleportation and to the study of information flows in quantum interactions.
