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…
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…
Entanglement from tensor networks on a trapped-ion QCCD quantum computer
Michael Foss-Feig, Stephen Ragole, Andrew Potter +9
The ability to selectively measure, initialize, and reuse qubits during a quantum circuit enables a mapping of the spatial structure of certain tensor-network states onto the dynam…
OD + CO -> D + CO2 Branching Kinetics Probed with Time-Resolved Frequency Comb Spectroscopy
Thinh Q. Bui, Bryce J. Bjork, P. Bryan Changala +3
Time-resolved direct frequency comb spectroscopy (TRFCS) was used to study the kinetics of the deuterated analogue of the OH+CO->H+CO2 reaction, which is important for atmospheric…
Methods, Analysis, and the Treatment of Systematic Errors for the Electron Electric Dipole Moment Search in Thorium Monoxide
ACME Collaboration, Jacob Baron, Wes C. Campbell +15
We recently set a new limit on the electric dipole moment of the electron (eEDM) (J. Baron et al., ACME collaboration, Science 343 (2014), 269-272), which represented an order-of-m…
Three Photon Absorption in Optical Parametric Oscillators Based on OP-GaAs
Oliver H. Heckl, Bryce J. Bjork, Georg Winkler +9
We report on the first singly-resonant (SR), synchronously pumped optical parametric oscillator (OPO) based on orientation-patterned gallium arsenide (OP-GaAs). Together with a dou…
Direct Frequency Comb Measurement of OD + CO -> DOCO Kinetics
Bryce J. Bjork, Thinh Q. Bui, Oliver H. Heckl +9
The kinetics of the OH + CO reaction, fundamental to both atmospheric and combustion chemistry, are complex due to the formation of the HOCO intermediate. Despite extensive studies…
Continuous probe of cold complex molecules with infrared frequency comb spectroscopy
Ben Spaun, P. Bryan Changala, David Patterson +4
Cavity-enhanced frequency comb spectroscopy for molecule detection in the mid-infrared powerfully combines high resolution, high sensitivity, and broad spectral coverage. However,…
Zeeman interaction in ThO for the electron EDM search
A. N. Petrov, L. V. Skripnikov, A. V. Titov +7
The current limit on the electron's electric dipole moment, (90% confidence), was set using the molecule thorium monoxide (T…
Order of Magnitude Smaller Limit on the Electric Dipole Moment of the Electron
ACME Collaboration, Jacob Baron, Wesley C. Campbell +15
The Standard Model (SM) of particle physics fails to explain dark matter and why matter survived annihilation with antimatter following the Big Bang. Extensions to the SM, such as…
Advanced Cold Molecule Electron EDM
ACME Collaboration, Wesley C. Campbell, Cheong Chan +11
Measurement of a non-zero electric dipole moment (EDM) of the electron within a few orders of magnitude of the current best limit of |d_e| < 1.05 e -27 e cm would be an indication…
Shot-noise-limited spin measurements in a pulsed molecular beam
E. Kirilov, W. C. Campbell, J. M. Doyle +9
Heavy diatomic molecules have been identified as good candidates for use in electron electric dipole moment (eEDM) searches. Suitable molecular species can be produced in pulsed be…
Magnetic and electric dipole moments of the state in ThO
Amar C. Vutha, Benjamin Spaun, Yulia V. Gurevich +5
The metastable state in the thorium monoxide (ThO) molecule is highly sensitive to the presence of a CP-violating permanent electric dipole moment of the electron (eE…
A cryogenic beam of refractory, chemically reactive molecules with expansion cooling
Nicholas R. Hutzler, Maxwell Parsons, Yulia V. Gurevich +7
Cryogenically cooled buffer gas beam sources of the molecule thorium monoxide (ThO) are optimized and characterized. Both helium and neon buffer gas sources are shown to produce Th…
Search for the electric dipole moment of the electron with thorium monoxide
Amar C. Vutha, Wesley C. Campbell, Yulia V. Gurevich +8
The electric dipole moment of the electron (eEDM) is a signature of CP-violating physics beyond the Standard Model. We describe an ongoing experiment to measure or set improved lim…
