Patent number: 11159168Abstract: Non-destructive read out (NDRO) circuits are provided for use in reciprocal quantum logic (RQL) superconducting systems. Each NDRO circuit includes a “body” circuit that provides a single or multi-state sub-critical bias current to one or many independent “tail” circuitries. Each “tail” has minimal effect on the “body” thereby preventing any interference or destruction to the state of the “body” circuitry. The circuits reduce device count and thereby increase circuit density, simplify and reduce the cost of fabrication, and provide functionality not available in existing designs, such as the ability to write a state and read it in the same operation cycle. The NDRO circuits provide more compact unit cells useful in memory or logic arrays, demanding fewer resources with increased functionality. The circuits also provide compact cells for AND, AND-OR, A-NOT-B, inverter, multiplexer, and demultiplexer gates.Type: GrantFiled: November 10, 2020Date of Patent: October 26, 2021Assignee: NORTHROP GRUMMAN SYSTEMS CORPORATIONInventors: Anna Y. Herr, Quentin P. Herr, Ryan Edward Clarke, Harold Clifton Hearne, III, Alexander Louis Braun, Randall M. Burnett, Timothy Chi-Chao Lee
