What`s the Matter?: Quantum Physics for Ordinary People
... Apparently, the measurement on the right side of the apparatus causes (in some sense of the word cause) the photon on the left side to be in the same quantum mechanical state, and this does not happen until well after they have left the source. This EPR “influence across space time” works even if th ...

It is the formalism of quantum mechanics that makes the testable predictions. • As long as an interpretation is consistent with the formalism, it will make the same predictions as any other interpretation, and no experimental tests are possible. • However, there is a ne ...

wave-particle duality
... The flux of particles arriving at the slits can be reduced so that only one particle arrives at a time. Interference fringes are still observed! Wave-behaviour can be shown by a single atom. Each particle goes through both slits at once. A matter wave can interfere with itself. Hence matter-waves ar ...

In their paper [1], Einstein, Podolsky, and Rosen define elements of physical reality as physical quantities, the values of which can be predicted with certainty ’without in any way disturbing the system’. They assume that every element of physical reality needs to have a counterpart in a complete p ...

Analysis of the famous experiment of Grangier, Roger, and Aspect

To resolve the ambiguity, the intervals are also drawn staggered below the lower line rather than on it. There seems no way to produce subscripts in “diagram mode”, so the intervals a ...
