Quantum entanglement zorgt ervoor dat twee aparte deeltjes op een willekeurige afstand van elkaar

SeekerOfTruth Crisp,

What about quantum entanglement of photons or electrons? Using an electron or photonic pair that is entangled at the quantum level, isn't it possible to transmit information instantaneously?
Crisp Hi SeekerOfTruth,

Very good question indeed, but I am not able to answer it. There is still a lot of research being conducted on quantum entanglement, and from what I've understood, it indeed seems to violate the laws of special relativity (let me note that there have been other quantum experiments that seem to violate relativity as well).

It could be a very promising way of communication (if we forget about practical problems about getting electrons or photons entangled), but I am afraid it will not be for the next 20 years or so. The effect is still not accepted by the general scientific community, even though more and more experiments are being conducted that point in favor of the quantum entanglement effect.

Anyway, I expect a major breakthrough to be made on that front somewhere soon (maybe in the next two years or so), so a little more patience before we get more information on entanglement .

Bye!

In "Quantum Entanglement" the two photons or electrons are the same particle in another dimension/s. Since they are in the same location, in another dimension, the force and interactions of these particles would be instantaneous. Maybe one day, when someone creates a split-quantum transmitter, this type of information transfer would be possible.

That seems like an interesting reply considering entangled photons have sucessfully been created in the proton teleport experiment conducted last year by 2 different groups - one at the Universtiy of Innsbruck and the other at the University of Rome.

( a brief mention in the 4th paragraph from the bottom - cant find a link to the original report atm )

Both EPR photons did seem to be in our current dimension ?
or am i not reading your reply correctly ?

Joeblow93132 MJC,

I meant that photons are a dual particle. They would exist in two dimensional planes. While in our dimensional plane(three dimensions + time) there would be two photons, in the other dimensional plane they may be only one particle. Since energy transfer can occur between these planes, one photon would always know what the other is doing.
