Read more Nanophotonics is at the forefront of research and development in scalable quantum technologies,ranging from quantum sensing to quantum computing. Traditionally, inherently weak photon-photonand photon-atom interactions in dielectric materials pose significant challenges to fully exploiting thepotential of these platforms. However, recent advances in the fabrication of nonlinear microresonatorswith nanometric features have allowed for the enhancement of all-optical interactions,necessitating new approaches to generating, controlling, and measuring quantum light.In this seminar, I will delve into unexplored regimes at the intersection of nonlinear and quantumoptics. I will begin by showcasing our latest advancements in developing integrated microresonatorsin thin-film 4H-Silicon Carbide. This innovation enables nonlinear photonics, quantum optics, andcollective quantum emitter excitations on the same platform. Following this, I will present ourexperimental demonstration of quadrature lattices of the quantum vacuum. This work shows howpulses that spontaneously emerge in microresonators can generate lattice dynamics of the quantumvacuum and how we can exert control over these dynamics.I will then discuss the broader implications of our findings, including enhanced interactions withquantum emitters, and ultrafast nonlinear quantum nanophotonics, which enable nonlinearinteractions at the single photon level. These outcomes pave the way toward new regimes of lightmatterinteractions that are enabled on scalable photonic microchips, with transformativeimplications for fundamental physics and quantum applications.Close abstract
