Excited-Band Coherent Delocalization for Improved Optical Lattice Clock Performance

Jacob Siegel, William McGrew, Youssef Hassan +5

We implement coherent delocalization as a tool for improving the two primary metrics of atomic clock performance: systematic uncertainty and instability. By decreasing atomic densi…

Mid-circuit operations using the omg-architecture in neutral atom arrays

Joanna W. Lis, Aruku Senoo, William F. McGrew +3

We implement mid-circuit operations in a 48-site array of neutral atoms, enabled by new methods for control of the (optical-metastable-ground state qubit) architectu…

Sub-recoil clock-transition laser cooling enabling shallow optical lattice clocks

X. Zhang, K. Beloy, Y. S. Hassan +5

Laser cooling is a key ingredient for quantum control of atomic systems in a variety of settings. In divalent atoms, two-stage Doppler cooling is typically used to bring atoms to t…

Ytterbium nuclear-spin qubits in an optical tweezer array

Alec Jenkins, Joanna W. Lis, Aruku Senoo +2

We report on the realization of a fast, scalable, and high-fidelity qubit architecture, based on Yb atoms in an optical tweezer array. We demonstrate several attractive pro…

Optical coherence between atomic species at the second scale: improved clock comparisons via differential spectroscopy

May E. Kim, William F. McGrew, Nicholas V. Nardelli +9

Comparisons of high-accuracy optical atomic clocks \cite{Ludlow2015} are essential for precision tests of fundamental physics \cite{Safronova2018}, relativistic geodesy \cite{McGre…

Characterization and suppression of background light shifts in an optical lattice clock

R. J. Fasano, Y. J. Chen, W. F. McGrew +3

Experiments involving optical traps often require careful control of the ac Stark shifts induced by strong confining light fields. By carefully balancing light shifts between two a…
