Description
Treating reference frames as physical systems, subject to the
laws of quantum mechanics, they become quantum reference
frames. Located at the interplay of quantum and gravitational
physics, their treatment marks an essential step towards the
construction of a relational quantum theory. In this work, we
introduce a relational formalism which identifies coordinate
systems with elements of a symmetry group G. We define a
general operator for reversibly changing between quantum
reference frames associated to a group G. This generalises the
known operator for translations and boosts to arbitrary finite
and locally compact groups, including non-Abelian groups.
