Quantum Mechanics & Spooky Action at a Distance

Presented by Prof. Allen Stairs, University of Maryland, Philosophy Department, Associate Chair. Einstein and Schrödinger both worried that quantum mechanics posits "spooky action at a distance." This was Einstein's phrase, and it referred to the fact that quantum mechanics seems to allow that what an experimenter does in one location can instantaneously affect things elsewhere. While Einstein and Schrödinger found this worrisome, others (mostly non-scientists) have embraced the idea, seeing it as evidence for some sort of hyper-connected reality. This talk will look at the underlying theoretical and experimental situation. In this talk, Prof. Stairs examines the notion of "quantum entanglement" and ask whether it's as spooky as it's sometimes cracked up to be.
