TL;DR: An approach to mechanical logic based on nanoelectromechanical systems that is a variation on the Parametron architecture is proposed and, as a first step towards a possible nanomechanical computer, both bit storage and bit flip operations are demonstrated.
Abstract: The Parametron was first proposed as a logic-processing system almost 50 years ago1. In this approach the two stable phases of an excited harmonic oscillator provide the basis for logic operations2,3,4,5,6. Computer architectures based on LC oscillators were developed for this approach, but high power consumption and difficulties with integration meant that the Parametron was rendered obsolete by the transistor. Here we propose an approach to mechanical logic based on nanoelectromechanical systems7,8,9 that is a variation on the Parametron architecture and, as a first step towards a possible nanomechanical computer10,11,12, we demonstrate both bit storage and bit flip operations.

TL;DR: In this article, a new Josephson junction logic device working on the principle of parametron and operated entirely on dc flux for input, output and excitation is discussed, and computer simulation of the device operation with clock signal of 100psec shows that the device is behaving very well as a logic element with low power dissipation.
Abstract: A new Josephson junction logic device working on the principle of parametron and operated entirely on dc flux for input, output and excitation is discussed in this article. Computer simulation of the device operation with clock signal of 100psec shows that the device is behaving very well as a logic element with very low power dissipation. The device's parameters and noise problems such as thermal noise and quantum tunnelling noise are also discussed. Promising results are obtained from the analysis.

TL;DR: Circuits of this family enable quasireversible computation with energy dissipation per bit much lower than the thermal energy, and hence may circumvent one of the main obstacles faced by ultradense three-dimensional integrated digital circuits.
Abstract: We analyze the operation of the wireless single-electron logic family based on single-electron-parametron cells. Parameter margins, energy dissipation, and the error probability are calculated using the orthodox theory of single-electron tunneling. Circuits of this family enable quasireversible computation with energy dissipation per bit much lower than the thermal energy, and hence may circumvent one of the main obstacles faced by ultradense three-dimensional integrated digital circuits.

TL;DR: In this paper, the authors experimentally demonstrate deterministic phase switching of a parametron by applying frequency tuning pulses and find different regimes of phase switching due to the interplay between a parametric pump and an external drive.
Abstract: The parametron, a resonator-based logic device, is a promising physical platform for emerging computational paradigms. When the parametron is subject to both parametric pumping and external driving, complex phenomena arise that can be harvested for applications. In this paper, we experimentally demonstrate deterministic phase switching of a parametron by applying frequency tuning pulses. To our surprise, we find different regimes of phase switching due to the interplay between a parametric pump and an external drive. We provide full modeling of our device with numerical simulations and find excellent agreement between model and measurements. Our result opens up new possibilities for fast and robust logic operations within large-scale parametron architectures.
