"The main message is that a lot of the properties that we think are very important, and in a way absolute, are relational or relative," said Anne-Catherine de la Hamette, a coauthor of the recent paper.
From one reference frame, we might observe the click of a detector happening at a certain time. But from a different reference frame, the click might end up in a superposition of happening before and after some other event.
Stepping into a quantum reference frame whose origin is in a superposition allows us to redefine the properties of gravity, enabling the calculation of gravitational fields for objects in superposition.
"By finding a convenient quantum reference frame, we can take a problem that we cannot solve [and make it] a problem we can solve," explained Viktoria Kabel, a researcher in Brukner's group.
