'Spooky Action At A Distance' Of Quantum Mechanics Directly Observed

ScienceDaily (Mar. 4, 2009) — In quantum mechanics, a vanguard of physics where science often merges into philosophy, much of our understanding is based on conjecture and probabilities, but a group of researchers in Japan has moved one of the fundamental paradoxes in quantum mechanics into the lab for experimentation and observed some of the 'spooky action at a distance' of quantum mechanics directly,

Hardy's Paradox, the axiom that we cannot make inferences about past events that haven't been directly observed while also acknowledging that the very act of observation affects the reality we seek to unearth, poses a conundrum that quantum physicists have sought to overcome for decades. How do you observe quantum mechanics, atomic and sub-atomic systems that are so small-scale they cannot be described in classical terms, when the act of looking at them changes them permanently?

You're welcome. I don't see any paradoxes here. Hardy's setup is given in Fig. 1 contained in this paper by Abramov. The arms are Mach-Zehnder interferometers. That means, only the C detectors will go off, because of constructive interference. The D detectors will never go off, because that path would have destructive interference, or the particles would be annihilated and there'd be nothing to set off the detector.

I also don't believe in "weak measurements". The weak "expectation values", or "observables" are expectation values divided by an amplitude. Of what use, or meaning is that?

If one wants to ponder spooky action at a distance, consider the particulars of B meson decay, subsequent to Upsilon(4S) decay. The ϒ(4S) is composed of a bottom quark(b) and an antibottom quark (¯b). It decays as in (d) in the following fig.(and link), where q and ¯q represent up(u), or down(d) quarks and their corresponding antiparticle.

Immediately after the ϒ(4S) decays, the 2 B particles exist as a pair of flavor oscillating particles. Neither particle takes on a definite identity, until one of them decays into a definite B^{0, or +/-}, or it's antiparticle. ie. B⁰<->¯B⁰, or B⁺<->¯B^-. Then the other particle can know what it must turn into. The decay of the 2nd B particle begins, with a particular rate corresponding to the decay of one of the 4 modes given in the link. Until one of the particles decays from the flavor oscillation, the other can not know what it must turn into. By the time it happens, the particles are too far apart for light speed comms to have an effect. The 2nd particle knows instantaneously what it must decay into.

This link has some more on that.

If information is not lost in a black hole, then consider the information from our own duality in having been alive, but gradually dead. Two sides to an equation.

If God is good - as I believe - then sorting out such energy would seem an early step on the way to heaven, or cutting all but consciousness for those bound for hell so they might observe what they otherwise might have shared.

“If I knew God I’d be Him.” ...But I know too that by Israel, meaning to “struggle”, and islam meaning to “submit”...I’ll yet struggle, thanks.
