Vacuum Fluctuation-Induced State Switching in Degenerate Optical Parametric Oscillators
Yihao Huang, Seou Choi, Rom Simovitch +5
Bistable driven-dissipative systems near bifurcations can exhibit noise-activated switching between steady states. Here, we investigate how quantum vacuum fluctuations induce such…
Quantum Skyrmions in Mixed States of Light and their Nested Topology
Amit Kam, Charles Roques-Carmes, Shai Tsesses +1
Topological quasiparticles of light, such as classical and quantum optical skyrmions, have so far relied on fully coherent or pure quantum states whose topology is encoded in the e…
A general framework for interactions between electron beams and quantum optical systems
Jakob M. Grzesik, Aviv Karnieli, Charles Roques-Carmes +5
We provide a theoretical framework to describe the dynamics of a free-electron beam interacting with quantized bound systems in arbitrary electromagnetic environments. This expands…
Variational processing of multimode squeezed light
Aviv Karnieli, Paul-Alexis Mor, Charles Roques-Carmes +5
Integrated multimode quantum optics is a promising platform for scalable continuous-variable quantum technologies leveraging multimode squeezing in both the spatial and spectral do…
Quantum sensing of electron beams using solid-state spins
Jakob M. Grzesik, Dominic Catanzaro, Charles Roques-Carmes +13
Scattering experiments with energetic particles, such as free electrons, have been historically used to reveal the quantum structure of matter. However, realizing coherent interact…
On-Chip Laser-Driven Free-Electron Spin Polarizer
Clarisse Woodahl, Melanie Murillo, Charles Roques-Carmes +3
Spin-polarized electron beam sources enable studies of spin-dependent electric and magnetic effects at the nanoscale. We propose a method of creating spin-polarized electrons on an…
