Dissipative preparation of qutrit entanglement via periodically modulated Rydberg double antiblockade.We propose a mechanism of Rydberg double antiblockade by virtue of a resonant dipole-dipole interaction between a pair of Rydberg atoms placed at short distances scaling as 1/R3.

By combining this novel excitation regime with microwave-driven fields and dissipative dynamics, a stationary qutrit entangled state can be obtained with high quality, the corresponding steady-state fidelity and purity are insensitive to the variations of the dynamical parameters.

Furthermore, we introduce time-dependent laser fields with periodically modulated amplitude to speed up the entanglement creation process.
