The weird and wonderful history of quantum entanglement that led to this year’s Nobel prize

06 Oct 2022 Hamish Johnston

This episode of the Physics World Weekly podcast focuses on the 2022 Nobel Prize for Physics, which is shared by Alain Aspect, John Clauser and Anton Zeilinger for their experimental work on the quantum entanglement of photons.

The physicist and historian of science David Kaiser is on hand to talk about the physics and philosophy of entanglement. He charts the history of the curious concept from the pioneering work of Albert Einstein and Erwin Schrödinger in the 1930s; through to the brilliant insights of John Stewart Bell in the 1960s; and on to the ground-breaking experiments of this year’s Nobel laureates. Kaiser, who is based at the Massachusetts Institute of Technology, talks about the early controversy surrounding entanglement and explains why the phenomenon was swept under the carpet by the wartime generation of physicists only to be revived in the 1960s.
