A two-eigenstate model near Förster resonances yields a gate fidelity bound F ≤ 1 - (π/2)/(V τ_R) saturated by a new protocol that improves prior limits by ~40%, with common protocols showing up to 100x higher fidelity when exchange dynamics are retained.

A modified asymmetric Rydberg gate protocol with target detuning and optimized phase waveforms achieves fidelity within a factor of 2.39 of the Rydberg lifetime limit outside the blockade regime.
Weak anharmonicity induces dissipation into dark states of photon-emitter pairs; first- and second-order perturbative corrections to the wavefunction are derived and applied to the master equation.
