A high fidelity light-shift gate for clock-state qubits
C. H. Baldwin, B. J. Bjork, M. Foss-Feig +7
To date, the highest fidelity quantum logic gates between two qubits have been achieved with variations on the geometric-phase gate in trapped ions, with the two leading variants b…
Optical Pumping of TeH+: Implications for the Search for Varying mp/me
Patrick Stollenwerk, Mark G. Kokish, Antonio G. S. de Oliveira-Filho +2
Molecular overtone transitions provide optical frequency transitions sensitive to variation in the proton-to-electron mass ratio (). However, robust molecular stat…
Prospects for Polar Molecular Ion Optical Probe of Varying Proton-Electron Mass Ratio
Mark G. Kokish, Patrick R. Stollenwerk, Masatoshi Kajita +1
Molecules with deep vibrational potential wells provide optical intervals sensitive to variation in the proton-electron mass ratio (). On one hand, polar molecules are of intere…
Raman sideband cooling of a 138Ba+ ion using a Zeeman interval
Christopher M. Seck, Mark G. Kokish, Matthew R. Dietrich +1
Motional ground state cooling and internal state preparation are important elements for quantum logic spectroscopy (QLS), a class of quantum information processing. Since QLS does…
Trapped Ion Chain Thermometry and Mass Spectrometry through Imaging
V. Rajagopal, J. P. Marler, M. G. Kokish +1
We demonstrate a spatial-imaging thermometry technique for ions in a one-dimensional Coulomb crystal by relating their imaged spatial extent along the linear radiofrequency ion tra…
Precision Measurement Method for Branching Fractions of Excited P1/2 States Applied to 40Ca+
Michael Ramm, Thaned Pruttivarasin, Mark Kokish +2
We present a method for measuring branching fractions for the decay of atomic energy levels to lower-lying states based on time-resolved recording of the atom's fluoresce…
