- Abstract summary: We report a driven-dissipative mechanism to generate stationary entangled $W$ states among strongly-interacting quantum emitters placed within a cavity.
The non-harmonic energy structure of the interacting ensemble allows this transition to be resonantly selected by the cavity.
Evidence of this purely dissipative mechanism should be observable in state-of-the-art cavity QED systems in the solid-state.

- Abstract: We report a driven-dissipative mechanism to generate stationary entangled $W$
states among strongly-interacting quantum emitters placed within a cavity.
Driving the ensemble into the highest energy state -- whether coherently or
incoherently -- enables a subsequent cavity-enhanced decay into an entangled
steady state consisting of a single de-excitation shared coherently among all
emitters, i.e., a $W$ state, well known for its robustness against qubit loss.
The non-harmonic energy structure of the interacting ensemble allows this
transition to be resonantly selected by the cavity, while quenching subsequent
off-resonant decays. Evidence of this purely dissipative mechanism should be
observable in state-of-the-art cavity QED systems in the solid-state, enabling
new prospects for the scalable stabilization of quantum states in dissipative
quantum platforms.

We propose a scheme to generate long-lived spin squeezing in an ensemble of solid-state qubits interacting with electromagnetic noise emitted by a squeezed solid-state bath.
Results show that the ensemble can exhibit steady-state spin squeezing under suitable conditions, paving the way for the generation of steady-state many-body entanglement in ensembles of solid-state spin defects.

In systems of light emitters subject to single-emitter or two-emitter driving, the steady state perturbed away from the U(1) limit exhibits spin squeezing.
Our main result is that in systems of light emitters subject to single-emitter or two-emitter driving, the steady state perturbed away from the U(1) limit generically exhibits spin squeezing.

emitters via two-photon excitation [49.1574468325115]
Two non-identical quantum emitters, when placed within a cavity and coherently excited at the two-photon resonance, can reach stationary states of nearly maximal entanglement.
We show that this mechanism is merely one among a complex family of phenomena that can generate both stationary and metastable entanglement when driving the emitters at the two-photon resonance.

Correlated quantum systems feature a wide range of nontrivial effects emerging from interactions between their constituting particles.
In nonequilibrium scenarios, these manifest in phenomena such as many-body insulating states and anomalous scaling laws of currents of conserved quantities.
We propose a giant rectification scheme based on the asymmetric interplay between strong particle interactions and a tilted potential.

We report a phenomenon occurring in open quantum systems by which virtual states can acquire a sizable population in the long time limit.
This means that the situation where the virtual state remains unpopulated can be metastable.
We show how these results can be relevant for practical questions such as the generation of stable and metastable entangled states in dissipative systems of interacting qubits.
