Superconducting latch system

摘要

A reciprocal quantum logic (RQL) latch system is provided. The latch system comprises an output portion that retains a state of the latch system, and a bi-stable loop that comprises a set input, a reset input and an output coupled to the output portion. A positive single flux quantum (SFQ) pulse on the set input when the latch system is in a reset state results in providing a SFQ current in the output portion representative of the latch system being in a set state.
