Localized control of large ion crystals in a Penning trap using a spatial light modulator
Allison L. Carter, Jennifer F. Lilieholm, Bryce B. Bullock +3
Penning ion traps as quantum platforms have primarily utilized global control and symmetric Dicke states for quantum simulation and sensing experiments. The introduction of local c…
Quantum simulation of the Dicke model in a two-dimensional ion crystal
Bryce Bullock, Sean R. Muleady, Jennifer F. Lilieholm +6
Quantum many-body systems driven far from equilibrium can exhibit phase transitions, chaos and entanglement, but probing these phenomena in large, nearly closed systems remains cha…
Optimizing Doppler laser cooling protocols for quantum sensing with 3D ion crystals in a Penning trap
John Zaris, Wes Johnson, Athreya Shankar +4
Large, 3D trapped ion crystals offer improved sensitivity in quantum sensing protocols, and are expected to be implemented as platforms in near-future experiments. However, numeric…
Many-Body Effects in Dark-State Laser Cooling
Muhammad Miskeen Khan, David Wellnitz, Bhuvanesh Sundar +6
We develop a unified many-body theory of two-photon dark-state laser cooling, the workhorse for preparing trapped ions close to their motional quantum ground state. For ions with a…
Parametric Amplification of Spin-Motion Coupling in Three-Dimensional Trapped-Ion Crystals
Samarth Hawaldar, N. Nikhil, Ana Maria Rey +2
Three-dimensional (3D) crystals offer a route to scale up trapped ion systems for quantum sensing and quantum simulation applications. However, engineering coherent spin-motion cou…
Adiabatic Cooling of Planar Motion in a Penning Trap Ion Crystal to Sub-Millikelvin Temperatures
Wes Johnson, Bryce Bullock, Athreya Shankar +3
Two-dimensional planar ion crystals in a Penning trap are a platform for quantum information science experiments. However, the low-frequency planar modes of these crystals are not…
Generating Einstein$\unicode{x2013}$Podolsky$\unicode{x2013}$Rosen correlations for teleporting collective spin states in a two dimensional trapped ion crystal
Muhammad Miskeen Khan, Edwin Chaparro, Bhuvanesh Sundar +4
We propose the use of phonon$\unicode{x2013}$mediated interactions as an entanglement resource to engineer Einstein$\unicode{x2013}$Podolsky$\unicode{x2013}$Rosen (EPR) correlation…
Numerical Simulations of 3D Ion Crystal Dynamics in a Penning Trap using the Fast Multipole Method
John Zaris, Wes Johnson, Athreya Shankar +2
We simulate the dynamics, including laser cooling, of 3D ion crystals confined in a Penning trap using a newly developed molecular dynamics-like code. The numerical integration of…
Bilayer crystals of trapped ions for quantum information processing
Samarth Hawaldar, Prakriti Shahi, Allison L. Carter +3
Trapped ion systems are a leading platform for quantum information processing, but they are currently limited to 1D and 2D arrays, which imposes restrictions on both their scalabil…
Rapid cooling of the in-plane motion of two-dimensional ion crystals in a Penning trap to millikelvin temperatures
Wes Johnson, Athreya Shankar, John Zaris +2
We propose a highly feasible technique with no experimental overhead to rapidly cool the in-plane degrees of freedom of large two-dimensional ion crystals in Penning traps. Through…
Robustness of the projected squeezed state protocol
B. J. Alexander, J. J. Bollinger, M. S. Tame
Projected squeezed (PS) states are multipartite entangled states generated by unitary spin squeezing, followed by a collective quantum measurement and post-selection. They can lead…
Phase-coherent sensing of the center-of-mass motion of trapped-ion crystals
M. Affolter, K. A. Gilmore, J. E. Jordan +1
Trapped ions are sensitive detectors of weak forces and electric fields that excite ion motion. Here measurements of the center-of-mass motion of a trapped-ion crystal that are pha…
