Phase-coherent sensing of the center-of-mass motion of trapped-ion crystals

November 9, 2020

Author(s)

Matthew Affolter, Kevin Gilmore, Elena Jordan, John Bollinger

Measurements of the center-of-mass motion of a trapped-ion crystal that are phase- coherent with an external force are reported. These experiments are conducted

Broadening of the drumhead mode spectrum due to in-plane thermal fluctuations of two-dimensional trapped-ion crystals in a Penning trap

November 5, 2020

Author(s)

Athreya Shankar, Chen Tang, Matthew Affolter, Kevin Gilmore, Daniel H. Dubin, Scott E. Parker, Murray Holland, John Bollinger

Two-dimensional crystals of ions stored in Penning traps are a leading platform for quantum simulation and sensing experiments. For small amplitudes, the out-of

Generating GHZ states with squeezing and post-selection

June 1, 2020

Author(s)

Byron Alexander, Hermann Uys, John Bollinger

Many quantum state preparation methods rely on a combination of dissipative quantum state initialization, followed by unitary evolution to a desired target

A stroboscopic approach to trapped-ion quantum information processing with squeezed phonons

October 24, 2019

Author(s)

Wenchao Ge, Brian C. Sawyer, Joseph W. Britton, Kurt Jacobs, Michael Foss-Feig, John J. Bollinger

In trapped-ion quantum information processing, interactions between spins (qubits) are mediated by collective modes of motion of an ion crystal. While there are

Quantum amplification of motion of a mechanical oscillator

June 21, 2019

Author(s)

Shaun C. Burd, Raghavendra Srinivas, John J. Bollinger, Andrew C. Wilson, David J. Wineland, Dietrich G. Leibfried, Daniel H. Slichter, David T. Allcock

Detection of the weakest forces in nature and the search for new physics demand increasingly sensitive measurements of the motion of mechanical oscillators
