Episode 70: Path Integrals and Entanglement with Ken Wharton

Jim talks with Ken Wharton about how to describe entangled states as sums over histories of particle paths using the path integral method.  He shows how this works for Bell-type experiments, entanglements swapping, delayed choice experiments, and the triangle network.  This leads to a second way to describe what happens quantum mechanically without introducing non-locality (but requiring other classical ideas to break down).Show Notes: http://frontiers.physicsfm.com/70
