Engineering quantum cooperativity and squeezing in solid-state platforms

SPICE Workshop on Quantum Spinoptics, June 18th - June 20th 2024

Jayakrishnan Muttathil Prabhakarapada Nair

Physical systems interact with their surroundings, leading to dissipation, which is often viewed as an obstacle for quantum technologies. However, recent progress in light-matter interfaces has revealed that correlated dissipation can be utilized to generate novel dynamical states of matter and entanglement in many-body quantum systems. In this talk, I will discuss how we have leveraged the insights from quantum optics to pave the way for the — yet uncharted — exploration of cooperative quantum phenomena in solid-state platforms consisting of an ensemble of solid-state defects interacting via a common magnetic reservoir. I will then present a protocol to engineer spin-squeezing in this solid-state spin-defect ensemble that relies solely on the application of a static magnetic field.
