Fast high-fidelity charge readout by operating the cavity-embedded Cooper pair transistor in the Kerr bistable regime

Bhargava Thyagarajan, Sisira Kanhirathingal, Benjamin L. Brock +3

Operating the cavity-embedded Cooper pair transistor (cCPT) in the Kerr bistable regime, we demonstrate single-shot resolution between two charge states that are apart. The…

Feedback stabilization of the resonant frequency in tunable microwave cavities with single-photon occupancy

S. Kanhirathingal, B. Thyagarajan, B. L. Brock +5

We successfully demonstrate low-frequency noise suppression in the resonant frequency fluctuations of a cavity-embedded Cooper pair transistor (cCPT) driven at single-photon occupa…

Fast and Ultrasensitive Electrometer Operating at the Single-Photon Level

B. L. Brock, Juliang Li, S. Kanhirathingal +3

We demonstrate fast and ultrasensitive charge detection with a cavity-embedded Cooper pair transistor (cCPT) via dispersive readout of its Josephson inductance. We report a minimum…

Charge sensitivity of a cavity-embedded Cooper pair transistor limited by single-photon shot noise

S. Kanhirathingal, B. L. Brock, A. J. Rimberg +1

Using an operator scattering approach, we analyze the quantum dynamics of an ultrasensitive electrometer -- a Cooper pair transistor embedded in a quarter-wave microwave cavity (cC…

A Nonlinear Charge- and Flux-Tunable Cavity Derived from an Embedded Cooper Pair Transistor

B. L. Brock, Juliang Li, S. Kanhirathingal +4

We introduce the cavity-embedded Cooper pair transistor (cCPT), a device which behaves as a highly nonlinear microwave cavity whose resonant frequency can be tuned both by charging…
