Abstract

A method for generating a voltage waveform includes providing an optical signal, which comprises one or more sequences of optical pulses, distributing the optical pulses via optical waveguides to a plurality of optical-to-electrical converter units, using the optical-to-electrical converter units to convert the optical pulses into electric driving current pulses, generating voltage pulses by driving Josephson junctions with the electric driving current pulses.
