Applied Physics Letters has published a paper (link: describing Josephson junction arrays driven with a mode-locked laser. The paper by VTT and collaborators is being promoted by the journal as an Editor’s Pick. This work paves the way for reducing the heat load and increasing the output frequency of Josephson Arbitrary Waveform Synthesizers, which can provide arbitrary quantized voltage waveforms. Due to the duality of Josephson voltage and CQPS current standards, optical signal generation may also become suitable for driving the current standard being developed in the Quantum e-leaps project.
