Quantum Accelerator-Multi-Parametric Quantum Transduction Between Microwave, Optical, and Mechanical States
Abstract
To harness their full potential for quantum information, communication, and sensing the best attributes of multiple quantum system need to be combined in both integrated devices and over larger scale networks. Here, we propose to couple three leading quantum technologies – superconducting microwave circuits for nonlinear quantum signal processing, nanomechanical resonators for transduction and long-lived information storage, and optical photons for long distance communication. We will develop ultra-low dissipation mechanical resonators that interface with both optical and electrical signals. We will develop a nonlinear parametric pumping protocol to transfer signals with high fidelity between these components, which differ widely in technology and frequency. Our envisioned hybrid device will act as a long-lived mechanical quantum memory to store delicate quantum states during computation and communication. Ultimately, our technology may provide a powerful tool to faithfully transduce signals between microwave and optical qubits, forming a gateway to long distance communication over optical networks for quantum systems that do not naturally couple to light.
