Errors are inevitable in information processing and transfer. While error correction is widely studied in engineering, the underlying physics is not fully understood. Due to the complexity and energy exchange involved, information transmission should be considered as a nonequilibrium process. In this study, we investigate the effects of nonequilibrium dynamics on error correction using a memoryless channel model. Our findings suggest that error correction improves as nonequilibrium increases, and the thermodynamic cost can be utilized to improve the correction quality. Our results inspire new approaches to error correction that incorporate nonequilibrium dynamics and thermodynamics, and highlight the importance of the nonequilibrium effects in error correction design, particularly in biological systems.
在信息处理和传输过程中,错误是不可避免的。虽然纠错在工程领域得到了广泛研究,但其背后的物理学原理尚未完全被理解。由于涉及到复杂性和能量交换,信息传输应被视为一个非平衡过程。在本研究中,我们使用无记忆信道模型来研究非平衡动力学对纠错的影响。我们的研究结果表明,随着非平衡程度的增加,纠错能力会提高,并且热力学成本可用于提高纠错质量。我们的结果启发了将非平衡动力学和热力学纳入其中的新的纠错方法,并突出了非平衡效应在纠错设计中的重要性,特别是在生物系统中。
