quantum entanglement

[lagged]

what do you guys think about the bell-state quantum eraser? how do you think the information is transmitted from one photon to the other?

does anyone think that the idea of "superpositions" exist not only at the quantum level? ie, you flip a coin in the dark, the coin is in a superposition of both heads and tales, until you turn the light back on (taking a measurement).

quantum entanglement is just plain stupid. its like you and i holding hand and being able to run through a wall....

dont even get me started on teleportation

well might as well start. how about telekinesis. found a site online a while ago when i was bored one day about controlling a flame with your mind if you sat there long enough and stared at a candle. i just ended up burning my retinas out lol

Quantum Leap is awesome.

so how do you explain the results of the bell-state "eraser" experiment?

come on not in this thread. im talking about a real testable experiment.

i believe anything is possible, im just saying that id like to keep the topic on quantum entanglement and in specific, the bellstate eraser experiment.

I think the bell state "eraser" experiment may be invalid because there may be a wave or photons bouncing back from the filter at A which then modifies the beam from the crystal heading to the 2 slits at B. If a person were to angle the polarization filter at A so any reflected photons missed the crystal and the original beams then it would disprove my physical interference theory. Maybe someone with the equipment should try it?

:wiggle: I like cheese.

I've heard that can be done with a properly tuned 2jz !

interesting point. however, i couldnt imagine that the physicists carrying out the experiments havent thought of that?

is there a better theory to explain this other than quantum entanglement?

supra8903, if you think it is stupid, why is that? there are experiments which are irrefutable. of course we do not exactly know what it is occuring, but you cant just step in and say its stupid. do you have any other explanation for the results? assuming that there was no errors in the tests.

 

[Aaron J Williams]

Ok, how about this then, suppose that the beam at A being filtered carries in itself a wave which travels back to the crystal and modifies the beam at B? In the same way that alternating current travels back and forth inside a wire, maybe a current or harmonic is carried back through the beam itself, using the beam as a conduit.

has it ever been demonstrated that light behaives in this way?

 

[Aaron J Williams]

Light can be defined as both energy and particle.

It would be reasonable to say that light particles (photons) would be reflected by the filter at A and could travel back through the beam or modify the wavelength of the beam which in turn modifies the beam at the crystal and therefore modifies the beam going to the 2 slits at B. You could postulate that the light at A would be absorbed by the filter at A, not reflected. If so, then the filter should change in temperature as the light is absorbed. If that is true then the temperature change at A filter would change the fiter's properties as the atoms in the filter are excited. This change could facilitate the reflection or change of the light wave which modifies the light wave back to the crystal. Even if the light is absorbed by the filter, not all photons will be absorbed. Some will stray away from the filter and possibly back to the crystal, maybe even changing the harmonics in the crystal itself and thus causing the apparent quantum entanglement. All of this is theoretical of course until someone does experiments to explore the possibilty.
