“From physical principles to quantum theory and beyond”


In the last few years, it has become clear that quantum theory is just one possible probabilistic theory among many others. This research, rooted in quantum information theory, has shown that physics could potentially behave very differently, predicting different kinds of correlations or interference patterns. In the talk, I will focus on two aspects of this research. First, I will show how one can derive the Hilbert space formalism of quantum theory from some simple information-theoretic principles. Second, this new perspective will make it clear that the structure of quantum mechanics is tightly linked to the structure of spacetime in several surprising ways. As time permits, I will show one or two rigorous theorems that demonstrate this relationship, for example a result that relates the number of degrees of freedom of a quantum bit to relativity of simultaneity on an interferometer.

STUDENTS – after the talk, you’re encouraged to return to the 2nd floor Atrium lounge to meet with the speaker.

COFFEE – coffee and cookies will be available in the 2nd floor Atrium lounge at 1:15 p.m.

CELL PHONES – as a courtesy to the speaker and audience, please set your cellphones to “silent” mode. Thanks!
