Reversible conveyer computation in array of parametric quantrons

A possibility of physically and logically reversible processing of digital information in Josephson-junction circuits of a reasonable complexity has been considered. As example, a 8-bit 1024-point fast convolver has been designed on the basis of a two-dimentional quasi-uniform array of\sim 250\times30,000parametric quantrons. This completely reversible conveyer device can operate with the estimated rate of at least\sim10^{9}numbers per second, which corresponds to\sim10^{14}binary logical operations per second. At this rate the power dissipation in the whole device can still be as low as ∼30nW. A new mode of the parametric quantron operation with larger parameter margins is also described.
