Suppression of differential light shifts in ground and metastable trapped-ion qubits
Drew Parks, Thomas Dellaert, Patrick McMillin +3
In the presence of a magnetic field, hyperfine clock qubits can acquire a vector differential light shift that can be tuned via polarization to suppress the total differential ligh…
Thermal light in confined dimensions for "laser" cooling with unfiltered sunlight
Amanda Younes, Wesley C. Campbell
Cooling of systems to sub-kelvin temperatures is usually done using either a cold bath of particles or spontaneous photon scattering from a laser field; in either case, cooling is…
Photon scattering errors during stimulated Raman transitions in trapped-ion qubits
I. D. Moore, W. C. Campbell, E. R. Hudson +3
We study photon scattering errors in stimulated Raman driven quantum logic gates. For certain parameter regimes, we find that previous, simplified models of the process significant…
Errors in stimulated-Raman-induced logic gates in Ba
Matthew J. Boguslawski, Zachary J. Wall, Samuel R. Vizvary +6
is illuminated by a laser that is far-detuned from optical transitions, and the resulting spontaneous Raman scattering rate is measured. The observed scatte…
Polyqubit quantum processing
Wesley C. Campbell, Eric R. Hudson
We describe the encoding of multiple qubits per atom in trapped atom quantum processors and methods for performing both intra- and inter-atomic gates on participant qubits without…
Quantum Error Correction with Metastable States of Trapped Ions Using Erasure Conversion
Mingyu Kang, Wesley C. Campbell, Kenneth R. Brown
Erasures, or errors with known locations, are a more favorable type of error for quantum error-correcting codes than Pauli errors. Converting physical noise into erasures can signi…
Blueprint for trapped ion quantum computing with metastable states
D. T. C. Allcock, W. C. Campbell, J. Chiaverini +7
Quantum computers, much like their classical counterparts, will likely benefit from flexible qubit encodings that can be matched to different tasks. For trapped ion quantum process…
Weak dissipation for high fidelity qubit state preparation and measurement
Anthony Ransford, Conrad Roman, Thomas Dellaert +2
Highly state-selective, weakly dissipative population transfer is used to irreversibly move the population of one ground state qubit level of an atomic ion to an effectively stable…
Determining Reaction Pathways at Low Temperatures by Isotopic Substitution: The Case of BeD+ + H2O
Tiangang Yang, Bin Zhao, Gary K. Chen +3
Trapped Be+ ions are a leading platform for quantum information science [1], but reactions with background gas species, such as H2 and H2O, result in qubit loss. Our experiment rev…
Quantum Gates Robust to Secular Amplitude Drifts
Qile David Su, Robijn Bruinsma, Wesley C. Campbell
Quantum gates are typically vulnerable to imperfections in the classical control fields applied to physical qubits to drive the gates. One approach to reduce this source of error i…
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…
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…
