I am currently an undergraduate student at the L3 of the Magistère de Physique d’Orsay, a course that belongs to the Paris-Saclay University, and as part of my studies I am doing a 2-month-long internship with Guilhem Doat and Augustin Vanrietvelde. The purpose of this internship is to become familiar with Quantum Reference Frames, and more precisely how the strong and weak approaches for describing them differ when we consider imperfect frames of references.
