Squeezing light with optomechanical and spin-light quantum interfaces
Gian-Luca Schmid, Manel Bosch Aguilera, Chun Tat Ngai +6
We investigate squeezing of light through quantum-noise-limited interactions with two different material systems: an ultracold atomic spin ensemble and a micromechanical membrane.…
Optical coherent feedback control of a mechanical oscillator
Maryse Ernzer, Manel Bosch Aguilera, Matteo Brunelli +5
Feedback is a powerful and ubiquitous technique both in classical and quantum system control. Its standard implementation relies on measuring the state of a system, processing the…
Adiabatic Quantum Zeno Dynamics of Bosonic Atom Pairs with Large Inelastic Losses
Manel Bosch Aguilera, Alexis Ghermaoui, Rémy Vatré +3
We report on experiments exploring the non-Hermitian dynamics of pairs of two-level atoms tightly confined in an optical lattice and driven by a near-resonant laser. Although spont…
Coherent feedback cooling of a nanomechanical membrane with atomic spins
Gian-Luca Schmid, Chun Tat Ngai, Maryse Ernzer +3
Coherent feedback stabilises a system towards a target state without the need of a measurement, thus avoiding the quantum backaction inherent to measurements. Here, we employ optic…
