近日，中国科学院理论物理研究所王东升团队研究了状态自适应量子纠错与容错量子计算。相关论文于2026年1月26日发表在《物理评论A》杂志上。

研究组提出了一种状态自适应量子纠错的理论框架，该框架弥合了量子计算与纠错范式之间的鸿沟。通过将量子态信息融入纠错过程，研究组建立了一个由量子互信息而非相干信息主导的新容量机制。这一方法揭示了与纠缠辅助协议的根本性联系。研究组展示了该框架在容错量子计算中的实际应用，阐明状态自适应性如何在不增加测量开销的前提下实现增强的纠错能力。该框架不仅深化了对量子信道容量的理解，还为当前量子计算平台提供了具有实施优势的解决方案。

Title: State-adaptive quantum error correction and fault-tolerant quantum computing

Abstract: We present a theoretical framework for state-adaptive quantum error correction that bridges the gap between quantum computing and error correction paradigms. By incorporating knowledge of quantum states into the error correction process, we establish a new capacity regime governed by quantum mutual information rather than coherent information. This approach reveals a fundamental connection to entanglement-assisted protocols. We demonstrate practical applications in fault-tolerant quantum computation, showing how state adaptivity enables enhanced error correction without additional measurement overhead. The framework provides insights into quantum channel capacities while offering implementation advantages for current quantum computing platforms.
