Abstract
Superconducting output amplifiers having return to zero to non-return to zero converters are described. An example superconducting output amplifier (OA) includes a first superconducting OA stage having a first DC-SQUID and a second DC-SQUID arranged in parallel to the first DC-SQUID. The superconducting OA includes an input terminal for receiving a single flux quantum (SFQ) pulse train. The superconducting OA includes a first splitter configured to split a first set of SFQ pulses corresponding to the SFQ pulse train into a first return to zero (RZ) signal and a second RZ signal. The superconducting OA includes a first return to zero to non-return to zero (RZ-NRZ) converter configured to convert the first RZ signal into a first non-return to zero (NRZ) signal for driving the first DC-SQUID, and a second RZ-NRZ converter configured to convert the second RZ signal into a second NRZ signal for driving the second DC-SQUID.
