SPICE Workshop on Quantum Spinoptics, June 18th - June 20th 2024
Eric Kleinherbers
Integrating color centers (e.g., nitrogen-vacancy centers) into a common magnetic solid-state environment is a promising research field as it combines key aspects of the fields of quantum optics and spintronics.
Here, we study how we can harness correlations in a magnetic medium to imprint a steady-state entanglement onto the color centers. To this end, a key ingredient is to bring the environment out of equilibrium in order to avoid the uncorrelated thermal Gibbs state. As two examples, we study i) the influence of spin pumping described by spin accumulation and ii) a driven system at a magnetic instability. The resulting nonlocal and dissipative coupling mediated by the environment enables steady-state entanglement.
