- Abstract: We propose a physical model to explain the phenomenon of photon depletion in
superconducting microwave resonators in the dispersive regime, coupled to
Josephson junction qubits, via short microwave pulses. We discuss the
conditions for matching the amplitude and phase of the pulse optimally within
the framework of the model, allowing for significant reductions in reset times
after measurement of the qubits. We consider how to deal with pulses and
transient dynamics within the input-output formalism, along with a reassessment
of the underlying assumptions for a wide-band pulse.
