What if quantum theory did not hold in all scenarios, or was only a limiting case of some broader theory? In this case, can we still meaningfully talk about phase and interference? In this talk, I will present key results from a project to generalize phase and interference into post-quantum theories. I will discuss the special role the uncertainty principle plays in enabling non-trivial dynamics, and draw conclusions about the possibility of non-classical algorithms for computation beyond quantum theory.
Andrew Garner is a quantum information theorist, who completed his DPhil at the University of Oxford, and is now a Research Fellow at the Centre for Quantum Technologies at the National University of Singapore. His has made notable contributions to the foundations of quantum theory, where he has pioneered a framework to extend phase beyond quantum theory. He is also interested in quantum thermodynamics and single-shot statistical mechanics.
