Cavity Mode Initialization via a Rabi Driven Qubit

Abstract

Microwave cavity modes with long coherence times are used in many different quantum computing systems. During normal operation of such systems, these modes, called memory modes, often need to be set to different coherent photonic occupations. In this work we present a novel technique we call Rabi Driven Reset in which the state of a memory mode is transferred into a decaying mode. This is done through a Rabi driven qubit which is coupled to both modes via sideband driving tones. The outcome of the method is the initialization of the memory mode at any required coherent state. Simulations are presented to demonstrate the effectiveness of this technique, along with a comparison to an existing coupling method. Our simulations predict an improvement of an order of magnitude in initialization times compared to existing methods.
