We describe and benchmark a new quantum charge-coupled device (QCCD) trapped-ion quantum computer based on a linear trap with periodic boundary conditions, which resembles a race track. The new system successfully incorporates several technologies cr

Holographic quantum algorithms for simulating correlated spin systems

Autor: Michael Foss-Feig, David Hayes, Joan M. Dreiling, Caroline Figgatt, John P. Gaebler, Steven A. Moses, Juan M. Pino, Andrew C. Potter

Publikováno v: Physical Review Research, Vol 3, Iss 3, p 033002 (2021)

We present a suite of “holographic” quantum algorithms for efficient ground-state preparation and dynamical evolution of correlated spin systems, which require far fewer qubits than the number of spins being simulated. The algorithms exploit the

Experiments with Highly-Ionized Atoms in Unitary Penning Traps

Autor: Shannon Fogwell Hoogerheide, Aung S. Naing, Joan M. Dreiling, Samuel M. Brewer, Nicholas D. Guise, Joseph N. Tan

Publikováno v: Atoms, Vol 3, Iss 3, Pp 367-391 (2015)

Highly-ionized atoms with special properties have been proposed for interesting applications, including potential candidates for a new generation of optical atomic clocks at the one part in 1019 level of precision, quantum information processing and

Suppression of midcircuit measurement crosstalk errors with micromotion

Autor: J. P. Gaebler, C. H. Baldwin, S. A. Moses, J. M. Dreiling, C. Figgatt, M. Foss-Feig, D. Hayes, J. M. Pino

Publikováno v: Physical Review A. 104

Mid-circuit measurement and reset are crucial primitives in quantum computation, but such operations require strong interactions with selected qubits while maintaining isolation of neighboring qubits, which is a significant challenge in many systems.

Spectroscopic analysis of M- and N-intrashell transitions in Co-like to Na-like Yb ions

Autor: Roshani Silwal, Dipti Dipti, Endre Takacs, Joan M. Dreiling, Samuel C Sanders, Amy Christina Gall, Hemalatha Rudramadevi B, John D Gillaspy, Yuri Ralchenko

Publikováno v: Journal of Physics B: Atomic, Molecular and Optical Physics.

The M-intrashell spectra from Co-like Yb43+ through Na-like Yb59+ ions produced in an electron beam ion trap (EBIT) at the National Institute of Standards and Technology have been studied in the extreme ultraviolet (EUV) range. A few N-intrashell tra

Identification and Plasma Diagnostics Study of Extreme Ultraviolet Transitions in Highly Charged Yttrium

Autor: Roshani Silwal, Endre Takacs, Joan M. Dreiling, John D. Gillaspy, Yuri Ralchenko

Publikováno v: Atoms, Vol 5, Iss 3, p 30 (2017)

Extreme ultraviolet spectra of the L-shell ions of highly charged yttrium (Y 26 + –Y 36 + ) were observed in the electron beam ion trap of the National Institute of Standards and Technology using a flat-field grazing-incidence spectrometer in the w
