  10. Continuous Variables Teleportation L. Vaidman,PRA49, 1473 (1994)  unknown shift , kick

  11. The EPR State = teleportation machine of a known spin up to a flip q, f spin measurement

  12. The EPR State = teleportation machine of a known spin up to a flip q, f q, f spin measurement

  13. The EPR State = teleportation machine of a known spin up to a flip q, f q, f spin measurement

  14. Many-Worlds Interpretation In the Universe is not moved from Alice to Bob q, f But in Teleportation it is moved! q, f q, f spin measurement mixture of and

  15. Teleportation q, f q, f In all worlds! mixture of and and and But after rotation we get q, f The information sent is only about in which world we are Local Bell measurements split the nonlocal world and the branching is the carier of the huge amount of information.

  16. Why teleportation is possible? We cannot measure (scan) Ψ Too much information to send We cannot clone Ψ We do not scan Ψ We do not clone Ψ

  17. Why teleportation is possible? We cannot measure (scan) Ψ Too much information to send We cannot clone Ψ We do not scan Ψ We do not clone Ψ Most of information is in branching of the world

  26. Aharonov-BohmEffect

  27. Aharonov-BohmEffect The solenoid causes a relative phase, but the time when the phase is gained depends on the choice of gauge, and therefore, it is unobservable.

  28. Aharonov-BohmEffect The solenoid causes a relative phase, but the time when the phase is gained depends on the choice of gauge, and therefore, it is unobservable.

  29. Aharonov-BohmEffect The solenoid causes a relative phase, but the time when the phase is gained depends on the choice of gauge, and therefore, it is unobservable.

  30. Aharonov-BohmEffect The solenoid causes a relative phase, but the time when the phase is gained depends on the choice of gauge, and therefore, it is unobservable.

  31. Aharonov-BohmEffect The solenoid causes a relative phase, but the time when the phase is gained depends on the choice of gauge, and therefore, it is unobservable.

  32. Paradox I At every place on the paths of the wave packets of the electron there is no observable action, but nevertheless, the relative phase is obtained.

  33. Paradox II The relative phase is observable locally, therefore the time of change of the relative phase can be observed, in contradiction with the fact that it is a gauge dependent property.
