Control and measurement in the bosonic cQED system

Team members: Seungwon Jin, Grace Pang

Abstract

This project characterizes a single superconducting microwave cavity dispersively coupled to a single transmon qubit, using standard circuit QED control and measurement techniques. We review the underlying theory of dispersive coupling and readout, then apply a set of standard measurement protocols to extract the key system parameters (coupling strength, dispersive shift, coherence times) and compare them with theoretical expectations.
