Quantum Measurements, Nonlocality and the Arrow of Time | | J. W. Moffat
; | | Date: |
2 Oct 1997 | | Subject: | gr-qc hep-th quant-ph | | Abstract: | A theory is developed which attempts to reconcile the measurements of nonlocal quantum observables with special relativity and quantum mechanics. The collapse of a wave function, which coincides with a nonlocal measurement by some macroscopic measuring device, is associated with the triggering of an absorber mechanism due to the interaction of the apparatus with the charges in the rest of the universe. The standard retarded electromagnetic field plus radiation damping is converted, for a short time during the collapse of the wave function, to an advanced field plus radiation. The reversal of the arrow of time during the wave function reduction permits communication in nonlocal quantum experiments at the speed of light, resolving paradoxes associated with measurements of correlated quantum states and special relativity. The absorber mechanism and the advanced field solution are consistent with conventional Friedmann-Robertson-Walker expanding universes. | | Source: | arXiv, gr-qc/9710019 | | Services: | Forum | Review | PDF | Favorites | |
