Quantum harmonic oscillator spectrum analyzers
Jonas Keller, Pan-Yu Hou, Katherine C. McCormick +5
Characterization and suppression of noise are essential for the control of harmonic oscillators in the quantum regime. We measure the noise spectrum of a quantum harmonic oscillato…

State Readout of a Trapped Ion Qubit Using a Trap-Integrated Superconducting Photon Detector
S. L. Todaro, V. B. Verma, K. C. McCormick +7
We report high-fidelity state readout of a trapped ion qubit using a trap-integrated photon detector. We determine the hyperfine qubit state of a single Be ion held in a su…
