Frequency-robust Mølmer-Sørensen gates via balanced contributions of multiple motional modes
Brandon P. Ruzic, Matthew N. H. Chow, Ashlyn D. Burch +5
In this work, we design and implement frequency-robust Molmer-Sorensen gates on a linear chain of trapped ions, using Gaussian amplitude modulation and a constant laser frequency.…
In situ detection of RF breakdown on microfabricated surface ion traps
Joshua M. Wilson, Julia N. Tilles, Raymond A. Haltli +4
Microfabricated surface ion traps are a principle component of many ion-based quantum information science platforms. The operational parameters of these devices are pushed to the e…
Mean exit time in irregularly-shaped annular and composite disc domains
Elliot J. Carr, Daniel J. VandenHeuvel, Joshua M. Wilson +1
Calculating the mean exit time (MET) for models of diffusion is a classical problem in statistical physics, with various applications in biophysics, economics and heat and mass tra…
Engineering the Quantum Scientific Computing Open User Testbed (QSCOUT): Design details and user guide
Susan M. Clark, Daniel Lobser, Melissa Revelle +13
The Quantum Scientific Computing Open User Testbed (QSCOUT) at Sandia National Laboratories is a trapped-ion qubit system designed to evaluate the potential of near-term quantum ha…
Mean exit time for diffusion on irregular domains
Matthew J Simpson, Daniel J Vandenheuvel, Joshua M Wilson +2
Many problems in physics, biology, and economics depend upon the duration of time required for a diffusing particle to cross a boundary. As such, calculations of the distribution o…
Observation of Dynamical Fermionization
Joshua M. Wilson, Neel Malvania, Yuan Le +3
We observe dynamical fermionization, where the momentum distribution of a Tonks-Girardeau (T-G) gas of strongly interacting bosons in 1D evolves from bosonic to fermionic after its…
Energy-dependent 3-body loss in 1D Bose gases
Laura A. Zundel, Joshua M. Wilson, Neel Malvania +3
We study the loss of atoms in quantum Newton's cradles (QNCs) with a range of average energies and transverse confinements. We find that the three-body collision rate in one-dimens…
Quantum distillation and confinement of vacancies in a doublon sea
Lin Xia, Laura A. Zundel, Juan Carrasquilla +4
Ultracold atomic gases have revolutionized the study of non-equilibrium dynamics in quantum many-body systems. Many counterintuitive non-equilibrium effects have been observed, suc…
