EPR paradox 90 years: Brief history, modern formulation, and connection to measurement incompatibility
May 15th marks 90 years of Einstein's most cited paper: the EPR paradox. In this talk, the EPR argument and the correspondence it led to between Einstein and Schrödinger are reviewed. This correspondence leads us naturally to Schrödinger's formulation of the problem as an action at a distance or "steering", as he coined the phenomenon. We then discuss how Schrödinger's notion of steering forms the basis for the modern quantum information formulation of the EPR effect. We also clarify the connection between entanglement and steering, as well as show a simple mathematical many-to-one connection between the EPR effect and the notion of measurement incompatibility.
Sandwiches will be provided for those who register before 13/5 lunchtime.
