Metamaterial-Boosted Quantum Electromechanical Transducer for Microwave-Optical Interfacing

Britton Plourde (Inventor), Matthew Lahaye (Inventor)

Research output: Patent


A quantum computing transducer having a dense, tunable superconducting metamaterial transmission line (SMTL) spectrum that can resonantly enhance sideband scattering. The resonant enhancement of scattering boosts the scattering rate, and hence also the microwave-to-optical-interface (MOQI) transduction efficiency. Moreover, the integration of mechanical elements with the SMTL to realize the MOQI yields a platform that can be readily interfaced on chip, such as in an integrated circuit, with superconducting-qubit architectures to facilitate the local implementation of two of the essential functionalities required for a quantum repeater, i.e., data egress/ingress and a quantum processing module.
