Title: Quantum reference frames: foundations and applications
Abstract: Every physical observation is made with respect to a frame of reference that is realized through a physical system. Ultimately, every physical system must obey quantum mechanics, so reference frames may show quantum properties. For this reason, Quantum Reference Frames (QRFs) [1] were introduced, along with a proposal of extension of the principle of covariance of physical laws to all QRFs. I will describe the main ideas that have been discussed in the literature and give some physical examples. I will also talk about one of the main applications of QRFs, namely a Quantum extension of the Einstein’s Equivalence Principle [2], and the proposal of an experimental test for this principle [3].
