US Patent 10911031 Superconducting circuit for processing input signals

Superconducting circuits for processing input signals are described. An example superconducting circuit includes a first portion configured to receive an input signal having a data pattern represented by edge transitions in the input signal. The superconducting circuit further includes a second portion configured to provide an output signal, where the superconducting circuit is configured to, without applying a direct-current (DC) offset to the input signal, output the output signal corresponding to the edge transitions such that the output signal is substantially representative of the data pattern despite not applying the DC offset to the input signal.
