Scientists have linked two diamonds in a mysterious process called entanglement that is normally only seen on the quantum scale.
Entanglement is so weird that Einstein dubbed it "spooky action at a distance." It's a strange effect where one object gets connected to another so that even if they are separated by large distances, an action performed on one will affect the other. Entanglement usually occurs with subatomic particles, and was predicted by the theory of quantum mechanics, which governs the realm of the very small...
Because energy must be conserved in closed systems (where there's no input of outside energy), the researchers knew that the "lost" energy had been used in some way. In fact, the energy had been converted into vibrational motion for one of the diamonds (albeit motion that is too small to observe visually). However, the scientists had no way of knowing which diamond was vibrating.
Then, the researchers sent a second pulse of laser light through the now-vibrating system. This time, if the light emerged with a color of higher frequency, it meant it had gained the energy back by absorbing it from the diamond, stopping its vibration...
If the two diamonds weren't entangled, the researchers would expect each detector to register a changed laser beam about 50 percent of the time. It's similar to tossing a coin, where random chance would lead to heads about half the time and tails the other half the time on average.
Instead, because the two diamonds were linked, they found that one detector measured the change every time, and the other detector never fired. The two diamonds, it seemed, were so connected they reacted as a single entity, rather than two individual objects.

my gosh, someone who remembers van Vogt!
We’re all in this together!
Quantum events crossing the great divide into normal space-time? Isn’t that interesting Albert? Of course it also appears to destroy causality, but that is just a theory until some one kills Schrödinger’s cat (or not).
I didn’t.
Thanks for all the kind remarks, and “you’re welcome” where apropos.
wastedyears & mnehring — AFAIK, Ursula LeGuin originated the Ansible in sci-fi.
ApplegateRanch & brivette — A.E. Van Vogt, that’s going back a ways, because I read some Van Vogt, and I gave up reading fiction (other than DNC press releases) almost 30 years ago. :’)
I think it’s a great quote. In God all things really do hold together.
And I didn't *think* you meant Hilbert space, as that refers (more or less) to computational methodology (e.g. complete sets, choice of basis).
So to my mind, that left supersymmetry and branes.
My apologies for misunderstanding.
Can you flesh out your point for those of us without a clue?
Cheers!
lol...
Because of entanglement, if I respond to one of your posts, that means I have also responded to the other.

It’s not a deep thought, really.
Minkowski’s incorporation of time as another dimension of space a top-knotch construct of the free imagination and of re-imaging the actual dynamics of the world, both. And the idea of the imaginary (based off the mathematical square root of -1) parts of that construct somehow relating to the spiritual worlds I have seen considered by a Torah scholar some years ago. Despite the utility of Minkowski’s formulation, and that of the more general concept of (x,y,z,t) being a perfectly acceptable and mundane theoretical n-dimensional space, I still do not accept in the realm of the physical non-theoretical world that time is a dimension like the 3 spatial dimensions. Time is something fundamentally different.
In regards to N-space I was being far more prosaic. Einstein circumscribed our 3-space local world with a hard “c”, the speed of light, beyond which nothing may move faster. Yet if there higher spatial dimensions, actual physical space dimensions, which by wrapping, twisting or scaling are not ordinarily perceptible, then the effects observed by quantum mechanics may still be explainable by them alone, and all still accord with a hard “c” and locality.
In fact it may be that the truer view is that our perceived 3-space dimensions are the tightly twisted ones. Picture that the two QM-entangled diamonds start located next to a point on a tightly wound spring of small diameter. We move one far away in the space as we perceive it, that movement along the curve of the spring proceeds at speeds less than “c”.
Yet, in the higher dimensional space which is only observable through quantum mechanical effects the two diamonds are still very close. We fire the laser at one, and the entangled one far away in our 3-d space reacts. But in the QM N-dimensional space the laser’s “action of observation” hits both, because they are still close, still local. In that space signal velocity is still hard limited by some N-dimensional “c”, per Einstein, but in that space the “observations of the diamonds” are very close.
The quote is hardly random. It is the express reply to the question “HOW” does it all work? Christ by HIS will, holds it together and when HE desires, it will pass away.
Either the article or the experiment is badly framed. Excitation of a vibrational mode in a crystal is due to the absorption of a photon of a certain frequency. That absorption does not change the frequency of the remaining photons in the light pulse (all of the same frequency because it is a laser). When the crystal gives up its vibrations, it will not increase the frequency of the photons in the interrogating laser pulse. Not worth trying to explain the observations if the experiment (or explanation) make no sense.
They’re not looking at the phase relationship between the two pulses. They’re looking at the light’s frequency. Moving one of the diamonds would introduce a phase shift, but that wouldn’t explain the frequency shift.
But even a single diamond, all by itself, can absorb and release energy via photons. The explanation for this is conventional and isn’t being tested here. I’m just wondering if the supposed entanglement is just an artifact of the synchronized wave front and nothing spooky.
So, are you implying that you are an expert in anti-quantum theory?
Don't take offense, you seem to know what you are talking about so I'm just asking a question.........Of cours I'm merely assuming you have at least a masters degree if not a PhD in quantum physics......

Thanks for explaining!
