Dark state spectroscopy in nonlinear waveguide quantum electrodynamics
Shay Nadel, Amir Sivan, Aviv Karnieli
Quantum systems face a fundamental trade-off: they must remain decoupled from the environment to maintain long coherence times, yet they require interactions with the environment t…
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…
