Abstract
Superconducting output amplifiers (OAs) including compound direct current-superconducting quantum interference devices (DC-SQUIDs) having both inputs driven by an input signal having the same phase and related methods are described. An example superconducting OA includes: (1) a first compound DC-SQUID having a first DC-SQUID and a second DC-SQUID, and (2) a second compound DC-SQUID having a third DC-SQUID and a fourth DC-SQUID. The superconducting OA includes a first driver configured to receive a single flux quantum (SFQ) pulse train and amplify a first set of SFQ pulses associated with the SFQ pulse train to generate a first signal for driving the first DC-SQUID and the second DC-SQUID. The superconducting OA further includes a second driver configured to receive the SFQ pulse train and amplify a second set of SFQ pulses associated with the SFQ pulse train to generate a second signal for driving the third DC-SQUID and the fourth DC-SQUID.
