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…

Sub-hertz optical transitions in excited Yb
Patrick McMillin, Hassan Farhat, William Liu +1
We present the observation of three semi-forbidden transitions in singly-ionized ytterbium from the metastable state. Owing to the long lifetimes of both t…
