Observation of a Topological Berry Phase with a Single Phonon in an Ion Microtrap Array

Justin F. Niedermeyer, Nathan K. Lysne, Katherine C. McCormick +11

Controlled quantum mechanical motion of trapped atomic ions can be used to simulate and explore collective quantum phenomena and to process quantum information. Groups of cold atom…

Observation of Many-body Dynamical Delocalization in a Kicked Ultracold Gas

Jun Hui See Toh, Katherine C. McCormick, Xinxin Tang +4

Contrary to a driven classical system that exhibits chaos phenomena and diffusive energy growth, a driven quantum system can exhibit dynamical localization that features energy sat…

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…

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…
