  Dissipative entanglement generation protocols embrace environmental
interactions in order to generate long-lived entangled states. In this letter,
we report on the anti-bunching dynamics for a pair of actively driven quantum
emitters coupled to a shared dissipative plasmonic reservoir. We find that
anti-bunching is a universal signature for entangled states generated by
dissipative means and examine its use as an entanglement diagnostic. We discuss
the experimental validation of plasmonically mediated entanglement generation
by Hanbury Brown-Twiss interferometry with picosecond timing resolution
determined by an effective two-qubit Rabi frequency, and we analyze the
robustness of entanglement generation with respect to perturbations in local
detunings, couplings, and driving fields.
