Discussing Quantum Non-Locality And Its Implications | Prof. Sandu Popescu

Hans Busstra, together with Essentia Foundation's research fellow, physicist Dr. Lídia Del Rio, talks to Prof. Sandu Popescu about quantum non-locality. Popescu is Professor of Physics at the University of Bristol and a Fellow of the Royal Society. He did pioneering work in what became the field of quantum information and has won both the John Stuart Bell Prize and the Dirac Medal. In our conversation we discussed these topics: 00:00 Intro 03:58 The superposition cannot be observed 04:17 We don't observe the superposition itself 06:18 That you can compute something doesn't mean you understand what's going on 09:13 Sandu on the double slit 12:35 Einstein & History Of Quantum Mechanics 15:42 The EPR paper 18:57 Bell test 21:49 The obscurity of the EPR paper: Sandu on the history of physics 25:03 On the shut up and calculate era 28:31 Bell was 30 yrs dormant 28:57 The importance of Bell's paper 30:59 Sandu explaining Bell 32:10 What Bell ruled out 36:29 What exactly is a no-go theorem? 40:30 The first Bell tests 42:21 Implications of Bell 51:31 Is metaphysics a matter of preference? 57:26 The counter intuitiveness of quantum mechanics 59:49 Sandu on the different interpretations of quantum mechanics 1:05:44 Time in quantum mechanics 1:08:04 Does 'looking' produce information? 1:11:17 Weak measurements, making measurements that are less disturbing... 1:13:51 Everything is a measurement 1:15:04 On the arrow of time in quantum mechanics 1:16:38 Schrödingers cat and past creation 1:22:34 Retro causality 1:24:31 Predicting rainbows: on the difference between quantum mechanics and classical physics 1:26:59 Is quantum mechanics related to parapsychological phenomena? 1:32:38 On consciousness causes collapse 1:37:05 Influencing random number generators? 1:41:02 Lidia's 'dreamed' experiment 1:42:12 Has quantum mechanics changed your outlook on life?
