Helios: A 98-qubit trapped-ion quantum computer
Anthony Ransford, M. S. Allman, Jake Arkinstall +183
We report on Quantinuum Helios, a 98-qubit trapped-ion quantum processor based on the quantum charge-coupled device (QCCD) architecture. Helios features Ba hyperfine…
Probing the Critical Point (CritPt) of AI Reasoning: a Frontier Physics Research Benchmark
Minhui Zhu, Minyang Tian, Xiaocheng Yang +61
While large language models (LLMs) with reasoning capabilities are progressing rapidly on high-school math competitions and coding, can they reason effectively through complex, ope…
Digital quantum magnetism on a trapped-ion quantum computer
Reza Haghshenas, Eli Chertkov, Michael Mills +56
Digital quantum matter -- realized when discrete quantum gates approximate continuous time evolution -- is susceptible to heating into chaotic, structureless states. If digitizatio…
Laser cooling trapped-ion crystal modes beyond the Lamb-Dicke regime
John P. Bartolotta, Brian Estey, Michael Foss-Feig +2
Laser cooling methods for trapped ions are most commonly studied at low energies, i.e., in the Lamb-Dicke regime. However, ions in experiments are often excited to higher energies…
The computational power of random quantum circuits in arbitrary geometries
Matthew DeCross, Reza Haghshenas, Minzhao Liu +49
Empirical evidence for a gap between the computational powers of classical and quantum computers has been provided by experiments that sample the output distributions of two-dimens…
A Race Track Trapped-Ion Quantum Processor
S. A. Moses, C. H. Baldwin, M. S. Allman +93
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 t…
Entropy transfer from a quantum particle to a classical coherent light field
John P. Bartolotta, Simon B. Jäger, Jarrod T. Reilly +4
In the field of light-matter interactions, it is often assumed that a classical light field that interacts with a quantum particle remains almost unchanged and thus contains nearly…
Speeding Up Particle Slowing using Shortcuts to Adiabaticity
John P. Bartolotta, Jarrod T. Reilly, Murray J. Holland
We propose a method for slowing particles by laser fields that potentially has the ability to generate large forces without the associated momentum diffusion that results from the…
Sawtooth Wave Adiabatic Passage in a Magneto-Optical Trap
John P. Bartolotta, Murray J. Holland
We investigate theoretically the application of Sawtooth Wave Adiabatic Passage (SWAP) in a 1D magneto-optical trap (MOT). As opposed to related methods that have been previously d…
Laser Cooling by Sawtooth Wave Adiabatic Passage
John P. Bartolotta, Matthew A. Norcia, Julia R. K. Cline +2
We provide a theoretical analysis for a recently demonstrated cooling method. Two-level particles undergo successive adiabatic transfers upon interaction with counter-propagating l…
Narrow-line Laser Cooling by Adiabatic Transfer
Matthew A. Norcia, Julia R. K. Cline, John P. Bartolotta +2
We propose and demonstrate a novel laser cooling mechanism applicable to particles with narrow-linewidth optical transitions. By sweeping the frequency of counter-propagating laser…
