随机涨落将是影响纳米尺度电子器件工作的主要因素。本文介绍了可以利用这种波动的电路架构，如果信号具有类似粒子（离散，基于令牌）的特性。我们定义了一个抽象的电路原语，虽然缺乏功能时，使用无波动的信号，成为普遍的波动时，允许。信号波动能力的关键在于探索电路状态空间的能力。此功能用于解决死锁情况，否则只能通过增加设计复杂性来避免死锁。本文中的结果表明，在未来的计算机设计中，信号波动，而不是要避免不惜任何代价的障碍，可能是一个重要的因素，以实现有效的操作。
Random fluctuations will be a major factor interfering with the operation of nanometer scale electronic devices. This article presents circuit architectures that can exploit such fluctuations, if signals have a particle-like (discrete, token-based) character. We define an abstract circuit primitive that, though lacking functionality when used with fluctuation-free signals, becomes universal when fluctuations are allowed. Key to the power of a signal’s fluctuations is the ability to explore the state space of a circuit. This ability is used to resolve deadlock situations, which could otherwise only be averted by increased design complexity. The results in this article suggest that in the design of future computers, signal fluctuations, rather than being an impediment to be avoided at any cost, may be an important ingredient to achieve efficient operation.
