If a homogen entanglement could be performed with same type of particles in billions of quick steps under a flat surface, like under a hoverboard, there should be a rapid growth of space-time under the surface that would counter-act gravity, or even teleport the "thingy" into space with no use of time - we would have a sort of wormhole that in principle could bring spaceships to the other stars in a blink of an eye...

It's a Leap for me to believe in Quantum Entanglements.

So a "single photon" is sent into the crystal and an "echo of the original photon" exits the crystal. The timing of the exit and the direction are what has been measured.

But isn't what goes on while the photon is within the crystal only inferred based on theoretical expectations? Is this not another black box experiment where the key events going on inside the box are merely *assumed*?

One physicist comments: “it would be a dream if you could make that visible to the naked eye,” and I think that is critical to a real advancement in our understanding of physics in the microcosm. We need to go beyond black box experiments and actually get some visual or other empirical verification of whether our assumptions are correct or wrong. We need transparent box experiments.

The "quantum correlations" that form the hall-mark of entanglement, can be reproduced by macroscopic images, on your own personal computer. The effect is not due to any "spooky action at a distance", but rather, is due to the fact that it is impossible to make uncorrelated (independent) measurements on any object that manifests only a single bit of information. Such objects rarely occur naturally, in the classical, macroscopic world, but they can nevertheless, be easily constructed. After being constructed, if their properties are then measured, they exhibit the so-called "quantum correlations", in spite of being entirely classical, and in spite of the fact that "detection efficiencies" are higher than that supposed to rule-out any possibility of a "detection loophole" in "loophole-free" experiments. The effect is ultimately due to the little-known fact, that the Heisenberg uncertainty principle is, in essence, the very definition of a single bit of information; hence, any object manifesting only a single-bit of information, will exhibit all the "weird", non-independent correlations, long associated with the uncertainty principle.
