Speaker

Barbara Soda

About the speaker: Barbara began her studies in Physics at the University of Zagreb, before coming to Waterloo for the PSI program. She then began her PhD at UCL with Jonathan Oppenheim before returning to complete it at UW/PI under the supervision of Lucien Hardy and Achim Kempf. Since then, she has worked as a Postdoctoral Research Fellow at Perimeter Institute, working on physics at the intersection of quantum information and gravity. 

Title

Motion as the infinitesimal limit of quantum teleportation

Abstract

We study teleportation over small distances, where the vacuum of a quantum field serves as the source of entanglement. We find that the kinetic energy term in the Schrödinger equation can be derived as a quantum teleportation-induced Brownian motion. Therefore, we find that the notions of teleportation and continuous quantum and classical motion are unified. We also find a possible information-theoretic meaning of the ħ constant, namely that it measures the amount of entanglement available in the quantum field's vacuum at infinitesimal distances.
