Preselected Quantum Optical Correlations
Two previously discovered effects in the intensity interference: a spin-correlation between formerly unpolarized photons and a spin entanglement at-a-distance between photons that nowhere interacted, have been used for a proposal of a new preselection experiment. The experiment puts together two photons from two independent singlets and makes them interfere at an asymmetrical beam splitter. A coincidental detection of two photons emerging from different sides of the beam splitter preselect their pair--companion photons (which nowhere cross each other"s path) into a nonmaximal singlet state. The quantum--mechanical nonlocality thus proves to be essentially a property of selection. This enables a loophole--free experimental disproof of local hidden-variable theories requiring detection efficiency as low as 67% and an exclusion of all nonlocal hidden-variable theories that rely on some kind of a physical entanglement by means of a common medium.
