Quantum amplification of boson-mediated interactions
S. C. Burd, R. Srinivas, H. M. Knaack +7
Strong and precisely-controlled interactions between quantum objects are essential for quantum information processing, simulation, and sensing, and for the formation of exotic quan…
Bang-bang shortcut to adiabaticity in the Dicke model as realized in a Penning trap experiment
J. Cohn, A. Safavi-Naini, R. J. Lewis-Swan +7
We introduce a bang-bang shortcut to adiabaticity for the Dicke model, which we implement via a 2-D array of trapped ions in a Penning trap with a spin-dependent force detuned clos…
Quantum amplification of mechanical oscillator motion
S. C. Burd, R. Srinivas, J. J. Bollinger +5
Detection of the weakest forces in nature and the search for new physics are aided by increasingly sensitive measurements of the motion of mechanical oscillators. However, the atta…
Unifying fast scrambling, thermalization and entanglement through the measurement of FOTOCs in the Dicke model
R. J. Lewis-Swan, A. Safavi-Naini, J. J. Bollinger +1
Scrambling of quantum information is the process by which information initially stored in the local degrees of freedom of a quantum many-body system spreads over its many-body degr…
Verification of a many-ion simulator of the Dicke model through slow quenches across a phase transition
A. Safavi-Naini, R. J. Lewis-Swan, J. G. Bohnet +7
We use a self-assembled two-dimensional Coulomb crystal of ions in the presence of an external transverse field to engineer a simulator of the Dicke Hamiltonian, an iconi…

A. Safavi-Naini, R. J. Lewis-Swan, J. G. Bohnet +7
We use a self-assembled two-dimensional Coulomb crystal of ions in the presence of an external transverse field to engineer a quantum simulator of the Dicke Hamiltonian.…
Amplitude sensing below the zero-point fluctuations with a two-dimensional trapped-ion mechanical oscillator
K. A. Gilmore, J. G. Bohnet, B. C. Sawyer +2
We present a technique to measure the amplitude of a center-of-mass (COM) motion of a two-dimensional ion crystal of 100 ions. By sensing motion at frequencies far from the C…
Steady-state spin synchronization through the collective motion of trapped ions
Athreya Shankar, John Cooper, Justin G. Bohnet +2
Ultranarrow-linewidth atoms coupled to a lossy optical cavity mode synchronize, i.e. develop correlations, and exhibit steady-state superradiance when continuously repumped. This t…
Vibration-induced field fluctuations in a superconducting magnet
J. W. Britton, B. C. Sawyer, J. G. Bohnet +3
Superconducting magnets enable precise control of nuclear and electron spins, and are used in experiments that explore biological and condensed matter systems, and fundamental atom…
Dynamical quantum correlations of Ising models on an arbitrary lattice and their resilience to decoherence
Michael Foss-Feig, Kaden R A Hazzard, John J Bollinger +2
Ising models, and the physical systems described by them, play a central role in generating entangled states for use in quantum metrology and quantum information. In particular, ul…
