Query: Controlling Rydberg excitations using ion core transitions in alkaline
  earth atom tweezer arrays   Scalable, local control over gate operations is an outstanding challenge in
the field of quantum computing and programmable quantum simulation with Rydberg
atom arrays. One approach is to use a global field to excite atoms to the
Rydberg state, and tune individual atoms in and out of resonance via local
light shifts. In this work, we point out that photon scattering errors from
light shifts can be significantly reduced if the light shift is applied to the
Rydberg state instead of the ground state, which can be realized in Rydberg
states of alkaline earth atoms using optical transitions in the ion core. As a
proof-of-concept, we experimentally demonstrate global control of Rydberg
excitations in a Yb optical tweezer array via light shifts induced by a laser
tuned near the Yb$^+$ $6s\rightarrow6p_{1/2}$ transition. We also perform
detailed spectroscopy of the induced light shift and scattering rates of the
$6sns$ $^3$S$_1$ Rydberg states and reveal the existence of satellite lines
where losses from autoionization are strongly suppressed. This work can be
readily extended to implement local gate operations in Rydberg atom arrays.
