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…
Feshbach resonances in -wave three-body recombination within Fermi-Fermi mixtures of open-shell Li and closed-shell Yb atoms
Alaina Green, Hui Li, Jun Hui See Toh +6
We report on observations and modeling of interspecies magnetic Feshbach resonances in dilute ultracold mixtures of open-shell alkali-metal Li and closed-shell Yb atoms…
Coherently displaced oscillator quantum states of a single trapped atom
Katherine C. McCormick, Jonas Keller, David J. Wineland +2
Coherently displaced harmonic oscillator number states of a harmonically bound ion can be coupled to two internal states of the ion by a laser-induced motional sideband interaction…
Quantum-enhanced sensing of a mechanical oscillator
Katherine C. McCormick, Jonas Keller, Shaun C. Burd +3
The use of special quantum states to achieve sensitivities below the limits established by classically behaving states has enjoyed immense success since its inception. In bosonic i…
