US Patent 12136923 Superconducting circuit multi-chip synchronization system

One example includes a superconducting circuit chip. The chip includes superconducting circuitry that operates based on a clock signal. The chip also includes a ring oscillator configured to receive a synchronization signal from a ring oscillator associated with another superconducting circuit chip. The ring oscillator is also configured to provide a trigger signal to the superconducting circuitry at a given phase of the clock signal relative to a phase of the clock signal of a trigger signal associated with the other one of the superconducting circuit chips based on the synchronization signal.
