A solid-state platform for cooperative quantum phenomena
Benedetta Flebus, 
Department of Physics, Boston College
The dissipation resulting from the coupling of a system with its environment is commonly viewed as a foe for quantum technologies. Nonetheless, recent developments at light-matter interfaces have shown that correlated dissipation can be harnessed into novel dynamical states of matter and
entanglement in many-body quantum systems. In this talk, I will discuss how we have recently capitalized on this knowledge from quantum optics to set the stage for the — yet uncharted — exploration of cooperative quantum phenomena in quantum hybrid solid-state platforms. I will first introduce a comprehensive formalism for the quantum many-body dynamics of an ensemble of solid-state spin defects interacting via the magnetic field fluctuations of a common solid-state reservoir, and then show that dissipative correlations can play a relevant role in a realistic experimental setup. Finally, I will discuss how our findings offer a pathway to novel quantum sensing modalities and schemes for realizing long-range qubit-qubit coupling.
