Whatever the final theory of quantum gravity turns out to be, it will need to reconcile the incongruent ways in which time appears in quantum mechanics and general relativity. Quantum mechanics treats time as a classical background parameter, which is different than the way other observables, such as position and momentum, are treated. In stark contrast, general relativity promotes time to a dynamical quantity in the sense that Einstein’s equations relate how clocks behave in relative motion or differing gravitational fields. The aim of this conference, geared at graduate students and above, is to discuss the full consequences of treating time as a quantum phenomena in light of the recent progress on information-theoretic and operational descriptions of time as quantum observable. Topics discussed will include indefinite causal structures, the Page-Wootters formalism, relational quantum mechanics, quantum reference frames, the problem of time, and experimental implications.
Territorial Land Acknowledgement
Perimeter Institute acknowledges that it is situated on the traditional territory of the Anishinaabe, Haudenosaunee, and Neutral peoples.
Perimeter Institute is located on the Haldimand Tract. After the American Revolution, the tract was granted by the British to the Six Nations of the Grand River and the Mississaugas of the Credit First Nation as compensation for their role in the war and for the loss of their traditional lands in upstate New York. Of the 950,000 acres granted to the Haudenosaunee, less than 5 percent remains Six Nations land. Only 6,100 acres remain Mississaugas of the Credit land.
We thank the Anishinaabe, Haudenosaunee, and Neutral peoples for hosting us on their land.
