The Superconductive Electronics (SCE) Group is developing single-flux-quantum electronic circuits for applications in wireless communications, neuromorphic computing, and quantum computing. More specifically, we are developing quantum-based circuits for waveform synthesizers1 for RF metrology, cryogenic on-chip signal processing, qubit control and readout, and neuromorphic synaptic training.2 We have also fabricated and tested some of the highest-speed SCE digital circuits in the world for potential applications in energy-efficient, high performance computing.3 Our vibrant laboratory has facilities and expertise in circuit design and simulation, nanofabrication, and cryogenic high-speed testing.
