Abstract
We demonstrate state-dependent optical lattices for the Sr optical qubit at the tune-out wavelength for its ground state. We tightly trap excited state atoms while suppressing the effect of the lattice on ground state atoms by more than 4 orders of magnitude. This highly independent control over the qubit states removes inelastic excited state collisions as the main obstacle for quantum simulation and computation schemes based on the Sr optical qubit. Our results also reveal large discrepancies in the atomic data used to calibrate the largest systematic effect of Sr optical lattice clocks.

Summary
For 87Sr, the induced two-body loss coefficient b, given by the difference of the two-body coefficients extracted from the underlying atomic decay curves, shows the same behavior with respect to detuning as Γ This behavior can be explained by an increased tunneling rate in the second lattice band, leading to increased evaporation, correlated exponential and two-body decay rates, and an increased uncertainty for Δ8t 7. We fit the Rabi oscillations with an analytic solution to the optical Bloch equations [49] and
