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).
