DESCRIPTION:Title: <a href="https://researchseminars.org/talk/QMFNoT/11/">
 Discussion: are there experiments proving or disproving time symmetry?</a>
 \nby Jarek Duda (Jagiellonian University) as part of QM Foundations & Natu
 re of Time seminar\n\n\nAbstract\nTime/CPT symmetry is at heart of many mo
 dels of physics\, like unitary evolution in quantum mechanics\, or Lagrang
 ian formalism we use from classical mechanics\, electromagnetism\, up to g
 eneral relativity and quantum field theories. However\, this symmetry is q
 uite nonintuitive\, very difficult to really accept – mainly due to ther
 modynamical counterarguments. \nLet us try to discuss these arguments\, es
 pecially experiment-based. I will present some for us to discuss (adding m
 ore is welcomed)\, for example: Wheeler’s\, delayed choice quantum erase
 r (DCQE)\, “asking photons where they have been”\, “photonic quantum
  routers”\, Shor algorithm as more sophisticated DCQE\, also: Anderson l
 ocalization (starting with rho~sin^2 in [0\,1])\, Born rule\, Bell violati
 on.\n
