Amplitude sensing below the zero-point fluctuations with a two-dimensional trapped-ion mechanical oscillator

June 29, 2017

Author(s):

Kevin A. Gilmore, Justin G. Bohnet, Brian C. Sawyer, Joseph W. Britton, John J. Bollinger

We present measurements of the amplitude of a center-of-mass (COM) motion of a two-dimensional ion crystal composed of 100 ions in a Penning trap. For motion...

Vibration-induced field fluctuations in a superconducting magnet

Author(s):

Joseph W. Britton, John J. Bollinger, Justin G. Bohnet, Brian C. Sawyer, Hermann Uys, Michael Biercuk

Superconducting magnets enable precise control of nuclear and electron spins, and are used in experiments that explore biological and condensed matter systems...

Quantum spin dynamics and entanglement generation with hundreds of trapped ions

June 15, 2016

Author(s):

Justin G. Bohnet, Brian C. Sawyer, Joseph W. Britton, Michael L. Wall, A M. Rey, Michael S. Foss-Feig, John J. Bollinger

Quantum simulation of spin models can provide insights into a variety of hard problems, including the competition between entanglement and decoherence in open...

"Perpendicular laser cooling with a rotating wall potential in a Penning trap"

April 26, 2016

Author(s):

Joseph W. Britton, Justin G. Bohnet, John J. Bollinger, Steven B. Torrisi

We investigate the impact of a rotating wall potential on perpendicular laser cooling in a Penning ion trap. By including energy exchange with the rotating...

Prospects for atomic clocks based on large ion crystals.

September 08, 2015

Author(s):

John J. Bollinger, Kyle Arnold, Elnur Haciyev, Chern Hui Lee, Eduardo Paez, M. D. Barrett

We investigate the feasibility of precision frequency metrology with large ion crystals. For clock candidates with a negative differential static...
