Superconductor output amplifier

An apparatus for amplifying a superconductor output, comprising:

• a superconductor delay element;
• a “start” input coupled to a superconductor delay element for generating a single flux quantum (SFQ) pulse in response to a first signal injected at the “start” input;
• an output coupled to the superconductor delay element;
• first and second superconductor reflectors coupled to opposite ends of the superconductor delay element for reflecting the SFQ pulse back and forth between the first and second superconductor reflectors, thereby generating a time-disperse plurality of SFQ pulses at the output;
• a “stop” input coupled to one of the first and second superconductor reflectors for interrupting a reflection of the SFQ pulse at the one of the first and second superconductor reflectors in response to a second signal at the “stop” input, thereby ending the time-disperse plurality of SFQ pulses at the output.
