[Blunderov] The light-bulb moment for me is "belonging, as they do, to a single quantum state". Best Regards. http://physics.about.com/b/a/113148.htm?nl=1 Clock synchronization with Entangled Photons Clock synchronization with entangled photons has been proposed as an idea and now demonstrated in an experiment. One of the important issues in the theory of special relativity is the synchronization of clocks. How close can be the time at one clock, t1, be to the time at a second clock, t2? Modern clocks have improved to such a level that the resolution and accuracy of the comparison techniques have become the limiting factors to determine the degree of synchronization, t1-t2. New ideas, exploiting the novel aspects of entangled photons, say that quantum mechanics can overcome the classical limit in regard to clock synchronization. Physicists at the University of Maryland, Baltimore County, have now confirmed the idea by doing an experiment in which two entangled photons are sent respectively to two detectors some distance apart. Pairs of entangled photons are produced in a nonlinear crystal and will retain a special quantum correlation between themselves (belonging, as they do, to a single quantum state) even if they were to move apart to distances of trillions of km. The Maryland physicists synchronized two distant clocks, each attached to a photodetector, by building up a statistical sampling of the clock responses, first sending a photon from one emerging beam to one detector while its mate went to the other detector, and then switching the entangled pairs to the opposite detectors. In this way, two clocks 3 km apart were synchronized within a picosecond. Synchronicity is of course critical in many areas of telecommunications, especially in GPS.

Good stuff, Blunderov.
That old "spooky" action at a distance.
I sometimes want to fire my PC through a couple of slits to see if it's a particle or a wave.
I KNOW my lan exhibits non-locality sometimes.
However, rhino reminded me that just the observation of the above experiment would most assuredly affect its outcome.

[Blunderov] Would it be correct to say that the quantum scale is a realm in which probability is the dynamic instead of causality do you think? I'd be much obliged if you, or anyone with a moment to spare, could enlighten me on this score.
In a similar vein, I'm wondering if, when we talk about a 'quantum state', whether one of the things we mean is a (universal) minimum possible segment of time? A whisker of time so brief that only the potential for an event can exist and no more? How does time relate to probability exactly?
Yours in much puzzlement.

Even further, I think it's “possibility” (as in Lotfi Zadeh's fuzzy-logic), rather than probability, that is the dynamic at the quantum scale...

First, read Bruce Sterling's "Distraction", and then read http://electionmethods.org.

[Blunderov] Thanks Erik. I think I found the answer here:
http://mathforum.org/epigone/geometry-research/shukraldin
(Most of it is inscrutable to me but all the mathematics seems to come down to:)
<snip> The larger issue here is whether the quantum (microscopic) world could come from the macroscopic/cosmological worlds by changing a real time argument to an imaginary time argument, and what exactly this would mean physically in mathematical physics. One can guess that the change corresponds to a *phase* change similar to change of phase from liquid to solid to gas or Bose-Einstein condensate or superfluid or superconductor or plasma, etc. Then the microscopic world is just a different phase from the macroscopic/cosmological world. The Schrodinger equation holds for the microscopic world, but the macroscopic and microscopic worlds are not completely isolated - the Schrodinger equation changes to its real version (2) at times determined by the macroscopic equation (2) and some other (discrete) constraints, or more precisely the waiting times between Poisson events are *projections* of the right-hand-side of (2) into the probability density function (pdf) space. The time geometry or (piecewise) trajectory CONTROLS itself by projecting itself into a probability space or probability density scenario AS THE OBJECT EVOLVES. In a sense, we may have the equation: 5) PROBABILITY = (TIME) GEOMETRY that relates the macroscopic/cosmological and microscopic worlds. Osher Doctorow</snip>
<wanders off to wonder about 'imaginary time'> Best Regards

I haven't forgotten this Blunderov.
I've just had a busy last few days and I want to try and give a decent (well, for me answer.
Hopefully tomorrow.
Later Dewd, Walter

Blunderov, Sorry this took so long, but hey, I'm a major procrastinator. And besides that, not being a professional physicist, it's all conjecture on my part anyway.
With that said, I have read several books on current theoretical string theory, both by Brian Greene: "The Elegant Universe: Superstrings, Hidden Dimensions, and the Quest for the Ultimate Theory" and "The Fabric of the Cosmos: Space, Time, and the Texture of Reality". Both I highly recommend. Greene has BY FAR the finest ability to explain very technical physics to the layperson.
In addition, I have read a few primers on more conventional NON-theoretical physics of the general-relativity, special-relativity, Newtonian and Quantum ilk.
Anyhow, I'll make a foolhardy attempt at considering your questions with purely gut-level, theoretical conjecture of the most amateurish quality.
[Blunderov] Would it be correct to say that the quantum scale is a realm in which probability is the dynamic instead of causality
[Walter] You're absolutely correct in picturing the quantum scale as a realm where probability is not only dynamic, but that dynamic is the ONLY game in the realm. IMHO, that dynamic, or what physicists like to refer to as the quantum "foam", is not only occuring at sub-Planck scales which are currently beyond any method of direct or indirect examination, they are roiling at such a frenetic pace that I really think they would defy examination even if they WEREN'T so infinitesimally small.
To make my short conjecture a tad longer, let me speculate that this quantum foam is possibly only one layer of a contiguous spectrum of layers that make up "our" particular physical universe. One could suppose that this contiguous spectrum of layers might begin at the bottom with pure, unadulterated, chaotic, elemental energy in its most fundamental form, and runs the gamut all the way to the densest, coldest, darkest matter with gravitational effects so tremendous that the matter has either reached a state of cold, stop-dead-in-its-tracks, maximum density, or tunnels to be the big-bang singularity event for some other universe, possibly one with different initial physical laws.
As they say, the universe is not only stranger than we imagine, it is stranger than we CAN imagine.
Current Superstring theory in physics bears this out. From the latest and best minds on that scientific roller-coaster, the general agreement now is that there are 11 (eleven) dimensions in our universe. And at least one of them appears to be thoroughly connected WITHOUT regard to known physical space-time limitations. This could go a long way toward explaining quantum entanglement or "spooky action at a distance" which is an experientially verified phenomenon. It could also provide a valuable avenue in it's ability to integrate general relativity and gravity and contribute to the much sought after "Theory of Everything" or "Unified Field" holy grail.
I've also seemed to glean, and rather subjectively I might add, that the part of the physical universe that we can see, feel, touch, smell, measure, etc. lies in the middle part of that contiguous spectrum of energy/matter, and that attempts to examine the outer boundaries of this entire spectrum will be very difficult indeed, although I am personally optimistic we will find a way to probe the seemingly unprobeable.
One other note. There also appears to be some conjecture in the Superstring theory world that "our" part of the physical universe that we experience, is a shadow world projected "upward", if you might, from the pure energy "base" toward the motionless dense matter end of the energy/matter spectrum.
And the projection apparatus "might" be in the form of "plucked" fundamental strings that are probably better characterized as infinitesimally small vibrating loops of energy.
I'll close on that highly conjectural piece of subjective doo-doo
Gooday,
Walter
