Manipulating quantum states of light with extreme nonlinearity
Interactions between bosons (nonlinearities) enable a powerful form of control over their quantum state. In optics, this fact permits the generation of squeezed states, entangled photon pairs, and single photon sources, which act as critical resources for metrology and quantum information. Despite many advances, the generation of quantum optical states is limited in comparison to the vast space of possible states. In this talk, I will present new ways to produce and manipulate quantum states of light by leveraging extreme nonlinearities such as strong time-dependence, highly sensitive bistability, and nonlinear non-Markovian dissipation. I will discuss how these concepts can enable new applications such as: tunable probabilistic bits (“p-bits”) from quantum optical vacuum fluctuations, entangled photon pairs at extreme ultraviolet frequencies, and deterministic generation of optical Fock and highly-squeezed states.
