Nanomechanical oscillators are an alternative platform for computation in harsh environments. However, external perturbations arising from such environments may hinder information processing by introducing errors into the computing system. Here, we simulate the dynamics of three coupled Duffing oscillators whose multiple equilibrium states can be used for information processing and storage. Our analysis reveals that, within experimentally relevant parameters, error correcting dynamics can emerge, wherein the system's state is robust against random external impulses. We find that oscillators in this configuration have several surprising and attractive features, including dynamic isolation of resonators exposed to extreme impulses and the ability to correct simultaneous errors.
纳米机械振荡器是在恶劣环境中进行计算的另一种平台。然而，此类环境产生的外部扰动可能会通过将错误引入计算系统来阻碍信息处理。在此，我们模拟了三个耦合的达芬振荡器的动力学，其多个平衡态可用于信息处理和存储。我们的分析表明，在实验相关参数范围内，可以出现纠错动力学，其中系统状态对随机外部脉冲具有鲁棒性。我们发现，这种配置下的振荡器具有几个令人惊讶且有吸引力的特性，包括对受到极端脉冲的谐振器进行动态隔离以及纠正同时出现的错误的能力。
