Entanglement and conservation

+ 0 like - 0 dislike
24 views

Is the following assertion sufficiently unique to merit a paper? Every absolute conservation law implies a corresponding form of entanglement, not just spin (angular momentum). Linear momentum conservation would for example entangle originating equipment with wave packets and help determine packet dispersion rates. Mass-energy entanglement would provide a different way to look at wave function "collapse," via nominally instantaneous exclusion of finding the same mass-energy at remote locations. I have no idea what $T_3$ would be. Even some types of approximate laws may have corresponding entanglements.

Peter, thank you, that is very helpful. I collect old papers and am ashamed to say I do not even have a copy of EPR in hand. Other than arguing that Einstein understood entanglement as far back as 1927 (5th Solvay) -- a history issue, not a research one. My interest thus is no more than an emphasis on diversity that was perhaps recognized better in the past.

Look back at the original EPR paper ... that didn't use spin-entanglement, but position and momentum. And down-conversion produces photons that are entangled with respect to frequency=energy. I also don't see why you need a conservation law to produce entanglement. I don't see what you're proposing that is new.
