Quantum reference frames: a relational perspective on nonclassical spacetime

Understanding the fundamental nature of gravity at the interface with quantum
theory is a major open question in theoretical physics. Recently, the study of
gravitating quantum systems, namely quantum systems sourcing a gravitational
field and interacting gravitationally, has attracted a lot of attention, thanks to the
possibility of realising these scenarios in the laboratory in the near future.
When a quantum system sources a gravitational field, spacetime is fundamentally
nonclassical. In this situation, also the notion of a reference frame needs to be
generalised to account for quantum features of spacetime, thus realising a quantum
reference frame (QRF). In this talk, I will introduce a formalism to associate a QRF
to the quantum state of a particle, and show examples of why QRFs can contribute
to formulate physics on nonclassical spacetime.
