Gaussian states have played an important role in the physics of continuous-variable
quantum systems. They are appealing for the experimental ease with which they can be …

Einstein-Rosen-Podolsky (EPR) steering or quantum steering describes the “spooky action
at a distance” that one party is able to remotely alter the states of the other if they share a …

Non-Gaussian states with Wigner negativity are of particular interest in quantum technology
due to their potential applications in quantum computing and quantum metrology. However …

Remote state preparation enables one to prepare and manipulate quantum state non‐
locally. As an essential quantum resource, optical cat state is usually prepared locally by …

Quantum correlations are at the core of current developments in quantum technologies.
Certification protocols of entanglement and steering, suitable for continuous-variable non …

We studied the effect of delocalized single-photon addition (DPA a ̂ 1†+ ei φ a ̂ 2†) on
two input modes containing four cases: two independent coherent states (CSs), two …

Multipartite Einstein-Podolsky-Rosen (EPR) steering and multimode quantum squeezing are
essential resources for various quantum applications. The paper focuses on studying a …

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 …
