摘要

量子纠错码的近似概念在量子信息和物理学中具有广泛的重要性，但却没有得到统一的理解。现在，在近似量子纠错和量子电路复杂性之间建立的一般严格联系揭示了广义量子编码的 "复杂性相图"--并为复杂量子系统创建了一个新的统一视角。

A general theory of quantum codes connecting quantum computation, complexity and physics

Approximate notions of quantum error-correcting codes hold wide importance across quantum information and physics, but are not cohesively understood. Now, general rigorous connections established between approximate quantum error correction and quantum circuit complexity reveal a ‘complexity phase diagram’ for generalized quantum codes — and create a new unifying lens on complex quantum systems.
