Fast high-fidelity charge readout by operating the cavity-embedded Cooper pair transistor in the Kerr bistable regime Open
Operating the cavity-embedded Cooper pair transistor (cCPT) in the Kerr bistable regime, we demonstrate single-shot resolution between two charge states that are $0.09e$ apart. The measurement is performed with 94$\%$ fidelity in a duratio…

Broadband Solenoidal Haloscope for Terahertz Axion Detection Open
We introduce the Broadband Reflector Experiment for Axion Detection (BREAD) conceptual design and science program. This haloscope plans to search for bosonic dark matter across the [10^{-3},1] eV ([0.24, 240] THz) mass range. BREAD propose…

Fast and Ultrasensitive Electrometer Operating at the Single-Photon Level Open
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 $14$ $μe/\sqrt{\mathrm{Hz}}$ with a …

Retrieving Quality Factors for Reflection & Transmission Measurements Open
This article presents pedagogical explanation of retrieving the resonance parameters $Q_{L}$, $Q_{o}$ and $Q_{c}$ from both reflection and transmission measurement of microwave resonator. Here $Q_{L}$ stands for the total or loaded quality…
