Internship: Bell nonlocality as a resource for quantum technologies – LKB

Deadline December 31st 2025

Contrat type: Internship

Keywords: Quantum correlations, quantum communication, quantum state engineering, quantum metrology

Position open at Laboratoire Kastler Brossel (LKB) in the Multimode Quantum Optics group.

In absence of nonlocal quantum correlations, Bell’s local hidden-variable model puts constraints on the measurement statistics. These constraints are at the root of Bell inequalities, but, in principle, they also put limitations on the use of our quantum states. In this project, we will focus on continuous-variable systems, which means that we deal with a bosonic system (e.g. light) upon which we perform homodyne measurements. Within the context of such systems, the student will have the choice to explore one of the following applications: quantum state engineering or quantum metrology.
