The Superconductive Electronics (SCE) Group is developing single-flux-quantum electronic circuits for applications in quantum information science, neuromorphic computing, wireless communications. More specifically, we are developing quantum-based circuits for the following applications: qubit control and readout for superconductor-based quantum computing [1]; neuromorphic synaptic training [2] for artificial intelligence and machine learning; and waveform synthesizers [3] for RF and wireless communications metrology. We have also fabricated and tested some of the highest-speed (> 300 GHz) SCE digital circuits in the world for potential applications in energy-efficient, high performance computing. Our vibrant laboratory has world-class facilities and expertise in circuit design and simulation, nanofabrication (qubits, resonators, synthesizers, digital logic), and cryogenic (0.01 K – 10 K) high-speed testing.
