Stochastic resonance is a counterintuitive concept: the addition of noise to a noisy system induces coherent amplification of its response.

Irreversible logic operations inevitably discard information, setting fundamental limitations on the flexibility and the efficiency of modern computation. To circumvent the limit imposed by the von Neumann–Landauer (VNL) principle, an important objective is the development of reversible logic gates, as proposed by Fredkin, Toffoli, Wilczek, Feynman, and others.

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.

We report the realization of a completely controllable high-speed nanomechanical memory element fabricated from single-crystal silicon wafers.

We demonstrate a silicon-based high-frequency nanomechanical device capable of switching controllably between two states at room temperature.

We present the effect of temperature on the switching characteristics of a bistable nonlinear nanomechanical beam.
