Post-doc position: Optical Quantum parameter estimation: from theory to experiments

by mattiawalschaers | Jan 31, 2023 | actu_en_home, blog, multimode-news, stage | 0 comments

Overview A fundamental task in quantum metrology is to identify the ultimate sensitivity limit in the estimation of a parameter encoded into a quantum state. Even under ideal conditions, when all technical noise sources are removed, quantum noise poses unavoidable...

Post-doc position: Large-scale non-Gaussian entanglement and applications

by mattiawalschaers | Jan 20, 2022 | actu_en_home, blog, multimode-news, stage

Scientific context Our group, the multimode quantum optics group of Laboratoire Kastler Brossel, pioneered many aspects of continuous variable (CV) approach to quantum optics. Our main objects of interest are the quadratures of the electric field, which are typically...

Two side of the same coin: EPR steering and Wigner negativity

Quantum physics in phase space Phase space is a useful tool to represent physical systems, such as the position and momentum of a particle, or the electric field of propagating light. It is common to describe quantum states of such systems by their Wigner function:...

Quantum computers require a range of properties. First of all, we want them to be programmable to tackle a wide range of different problems. Furthermore, we also want them to be scalable, which means that we can put fundamental building blocks together to build a...
