Why Did Quantum Entanglement Win the Nobel Prize in Physics?
Original upload · 20:33
The 2022 Nobel Prize in Physics recognised experiments that made quantum entanglement harder to dismiss as a philosophical puzzle. PBS Space Time connects the work of John Clauser, Alain Aspect and Anton Zeilinger with Bell’s inequalities and the effort to test competing accounts of quantum correlations. This archival episode gives the collection an experimental and historical companion to minutephysics’s visual introduction to Bell’s theorem. The interest lies in what the experiments ruled out under their assumptions and how the tests improved. Neither the prize nor entanglement itself demonstrates a useful quantum-computing speedup or a way to send messages instantaneously.
