Latest Patents

Hearne's most recent patents encompass groundbreaking advancements in superconducting non-destructive readout circuits (NDRO). These innovative circuits are designed for use in reciprocal quantum logic (RQL) superconducting systems. Each NDRO circuit features a 'body' circuit that delivers a single or multi-state sub-critical bias current to one or multiple independent 'tail' circuitries. The design ensures minimal interference with the 'body' circuitry, effectively preserving its state. This innovative approach not only reduces device count and enhances circuit density but also simplifies the fabrication process. Furthermore, the NDRO circuits enable the ability to write a state and read it within the same operation cycle, which is unprecedented in existing designs. These circuits provide more compact unit cells that are advantageous in memory and logic arrays, minimizing resource demands while significantly boosting functionality. Additionally, they offer compact implementations for various gates such as AND, AND-OR, A-NOT-B, inverter, multiplexer, and demultiplexer.
