In the last half century, we’ve witnessed transformative changes in society enabled by computing technology. Presently, a new revolution in computation is taking place in which we’re rethinking everything from hardware to architecture. For example, the integration of optical components with traditional electronics is occurring rapidly. Photons and electrons offer complimentary attributes for information processing. Electronic effects are superior for computation and memory, while light is excellent for communication and I/O. Leveraging the strengths of both becomes crucial for systems with distributed memory and massive connectivity. My research is at the confluence of integrated photonics and superconducting electronics with the aim of developing superconducting optoelectronic networks. A principal goal is to combine waveguide-integrated few-photon sources with superconducting single-photon detectors and Josephson circuits to enable a new paradigm of large-scale neuromorphic computing. Photonic signaling enables massive connectivity. Superconducting circuitry enables extraordinary efficiency. Computation and memory occur in the superconducting electronic domain, while communication is via light. Thus, the system utilizes the strengths of photons and electrons to enable high-speed, energy-efficient neuromorphic computing at the scale of the human brain.
