Resumé des notions qu’on a vu dans ce cours:
- Prouver qu’un système est intriqué (exemple de la méthode)
- EPR Paradox (et variable cachée) [vidéo très intéressante et qui résume bien]
- FTL (quelques hints, pas de manière explicite)+
- Bell inequality:
- Loopholes in Bell experiments:
There may be problems of experimental design or set-up that affect the validity of the experimental findings. These problems are often referred to as « loopholes ».
The most prevalent loopholes in real experiments are the detection (detection efficiency) and locality loopholes.
– The detection loophole is opened when a small fraction of the particles (usually photons) are detected in the experiment, making it possible to explain the data with local hidden variables by assuming that the detected particles are an unrepresentative sample.
– The locality loophole is opened when the detections are not done with a spacelike separation, making it possible for the result of one measurement to influence the other without contradicting relativity. In some experiments there may be additional defects that make local-hidden-variable explanations of Bell test violations possible
