Finite trap strength makes subradiant atomic-array dark states decay faster over time, heat up, and lose fidelity; infidelity scales as (γ0η/ωt)^2 and is minimized with strong traps and perpendicular polarization.
These infidelities from the mixing of the excited states are compared to the decay infidelity in- dicated by the horizontal line

Effects of finite trapping on the decay, recoil, and decoherence of dark states of quantum emitter arrays
Finite trap strength makes subradiant atomic-array dark states decay faster over time, heat up, and lose fidelity; infidelity scales as (γ0η/ωt)^2 and is minimized with strong traps and perpendicular polarization.
