我们提出了一个纳米机械装置，作为一个可重新编程的逻辑门，并执行基本的逻辑功能，如and /OR和NAND/NOR。通过调整谐振器的工作参数，可以对逻辑功能进行动态编程（例如，从与到或）。该器件可根据特定的逻辑功能进入两种稳定的稳态之一；这个操作是由可以直接调整的噪声底调节，或者通过调整谐振器的潜在非线性来动态“调谐”，也就是说，不需要直接控制噪声底。这种可重新编程的纳米机械逻辑门的演示为新一代机械计算机的实际实现提供了一条途径。
We present a nanomechanical device, operating as a reprogrammable logic gate, and performing fundamental logic Functions such as AND/OR and NAND/NOR. The logic function can be programmed (e.g., from AND to OR) dynamically, by adjusting the resonator's operating parameters. The device can access one of two stable steady states, according to a specific logic function; this operation is mediated by the noise floor which can be directly adjusted, or dynamically "tuned" via an adjustment of the underlying nonlinearity of the resonator, i.e., it is not necessary to have direct control over the noise floor. The demonstration of this reprogrammable nanomechanical logic gate affords a path to the practical realization of a new generation of mechanical computers.
