One other thing that makes this interesting, even though it might be slightly outside this conversation? Is 'Interaction Free Measurements'. And it has a relevance, as I see it, to how we define this 'wave collapse'. Because that's the first step for me ever going to see what a entanglement might be.


"Another very interesting topic is that of a quantum object, i.e., one that can be in a superposition of being "there" and "not there". One such example is an atom in an atom interferometer, which simultaneously exists in both arms. Another is the recent separated-ion demonstration by Wineland et al., in which a single ion in a trap is made to coexist at two separated points in space.

If such systems are evaluated using the interaction-free measurement schemes, then the two sub-systems -- the quantum object and the interrogating light -- become entangled. In fact, although we have not discussed it at all here, for sufficiently large N, the interaction-free measurement methods even work for multiple-photon states, even for dim classical pulses.

Therefore, combining such an input with a quantum object, one is able to transfer the quantum superposition of the latter onto the former. In other words, one could make superpositions of "bunches" of photons; for example, one could prepare a pulse of light with an average of 20 photons in it, all of whom were horizontal, or all of whom were vertical, and yet until a measurement was made, none of them would have a definite polarization. Such a peculiar state of affairs would be a modest example of a Schroedinger cat."

Trust is a dangerous thing DA :)
Yup, absolutely! But you can always trust a mushy avocado, yummy! :smile:

Lovely picture. And yes, entanglements is one of, or, the most confusing thing I know of.
Agree, the only consolation is that we’re in good company, no one understands entanglement 100%!
(As I see it, you’ve got all 'weirdness' in QM in one place; the measurement problem, wave/particles, probability, non-locality, HUP, RoS – and it’s just wonderful! :smile:)

How about what's setting a entanglement? The beam splitter does it, but I can't know the polarisation/spin without first measuring, right?
Well... eh... um... actually, you can’t say that it does... :uhh:

We could agree that a photon 'bouncing' in a mirror is kinda 'measured', right? But what about a photon going just straight thru a mirror (BS)? That can’t be a 'measurement'... or? :uhh:

Check this out:

Photons are emitted one at a time from the yellow star. They each pass through a 50% beam splitter (green) that reflects 1/2 of the photons, which gives two possible (red/blue) traveling paths.

In the top picture it’s no doubt which path the photon took, right?

But what happens when you insert another beam splitter, as in the lower picture? Well if the length of the path is exactly equal (through + reflected / reflected + through) – you can’t tell which path! :bugeye:

This is a standard setup for Alice’s and Bob two detectors:

To be absolutely "sure" (if this is 'feasible' in QM I don’t know... ;), you have to wait for the "click" in the yellow detectors.

... and then you can start the fight with Einstein, on who "did it" first! :wink:

Here’s a video on a standard EPR-Bell experiment:

Well, it's true with present day technology. But, the question is whether it's theoretically impossible to create macroscopic objects or future technologies can be able to do that.

Forgive me for jumping in here with questions, I have not read the entire thread, or much about your theory other than what came from technology review website. My question is probably asked a lot so here goes. If you can teleport energy over unlimited distances, light years, than could you somehow relay messages utilizing this theory?

I envision something like a binary code for passing on messages this way, this could be significant for obvious reasons. Do entangled protons occur in space, and if so would you be able to find one and look for messages from other parts of space?

If you can make a binary system that sends 1 entangled proton for 0 and 2 entangled for 1, then you'd be able to interpret this and create a binary message capable of interstellar travel, and maybe intergalatic.

It could also be used to create a high tech internet system, and much more here in our own solar system. You could power drones in space remotely, and have nearly instant communications.

Welcome to PhysicsForums, D.Blackburn!

This thread should really be closed and a new one started.

The short answer is: energy cannot be teleported in the manner in which you envision, nor in the manner you might conclude from the original post. That is simply incorrect.

Additionally, you cannot signal faster than c using entanglement or any other know mechanism.

Again, start a new thread to discuss further if needed. We don't need to re-hash discredited ideas.

According to this article they claim he can send electricity almost any distance.

That article is an inadequate source by forum rules. See:

https://www.physicsforums.com/showthread.php?t=414380

Even as a newbie, I think you know that energy cannot be teleported as implied by the article. That is because the direction and amount of energy nets to zero every time. There are conservation considerations, among others.

I am recommending this thread be closed. If you have a suitable subject to discuss, please open a new thread. But please do not reference this article again.

Agreed.

Note also that the reference is a pop-sci reference and that the arxiv article that it references is unpublished. That is not up to the PF standards, particularly since it seems to conflict with known physics.
