Transformed Composite Sequences for Improved Qubit Addressing

open access: yes, 2014
Selective laser addressing of a single atom or atomic ion qubit can be improved using narrowband composite pulse sequences. We describe a Lie-algebraic technique to generalize known narrowband sequences and introduce new sequences related by dilation and
