Runaway pulsar has astronomers scratching their heads

Information has a fairly technical meaning, but I think it comes down to whether a bit of information can potentially change something.

The entangled particle scenario does not allow this form of information to be transmitted.

Not as yet. But according to wikipedia, there is a lot of money being invested in the field, with a view to using the phenomenon in computing and communication. So they must view it as having potential to transmit readable information.

Quantum entanglement is an area of extremely active research by the physics community, and its effects have been demonstrated experimentally with photons, electrons, molecules the size of buckyballs,[11][12] and even small diamonds.[13][14] Research is also focused on the utilization of entanglement effects in communication and computation.

I have a feeling that the constant attempts to find something (matter or information) that goes faster than the speed of light are akin to trying to find exceptions to the second law of thermodynamics, and create a perpetual motion machine......

Or rather, "I read something in teh Daily Blurb that says that pasta can travel faster than light and I read it so I am clevererer than Einstein even though I left school at 15 to become a burger chef. Burger chefs are COOL!"

[FBM]

Only bacon burger chefs are cool.

Edit: OK, in the interest of fairness, bacon cheeseburger chefs.

If simultaneous measurements are taken a distance apart, it is actually impossible to say which affects which as both appear to occur before the other from its POV!

But that is only if you think locality exists and regard the particles to be separated by the speed of light, which is the basic assumption these experiments defy.

It sounds very much like there is a component of space time that is common throughout the universe.
Maybe it's supplied by another universe.
I remember some speculation that the speed of light might be got around, by dumping information into a parallel universe, and having it come back out millions of light years away.
That seems remarkably similar to what's happening with the entangled particles.

As far as I can see, information IS being sent faster than the speed of light.
The fact that we can't read it doesn't change that. The principle is there, even if the practicalities prevent any use being made of it at present. If you can affect the spin of a particle instantly, at a distance of a million light years, what else can you do?

I thought that relativity theory would be disproved, if information could travel faster than light?

Theoretically it can change something. That's what quantum computing is all about.

NO.

[pErvinalia]

YES

[Xamonas Chegwé]

YES

You clearly don't even understand what quantum physics isn't!

[pErvinalia]

I know what quantum physics isn't, but what aren't you?!!

[Xamonas Chegwé]

Ladies and gentlemen. I therefore offer you proof that ignorance can travel faster than light. Even faster than light that's having a particularly fasty day and is in one hell of a hurry!

[mistermack]

Well, the guy who wrote the wikipedia article certainly understands that there is serious work going on, to investigate using quantum entanglement in communication and computing.
As computing and communication both involve the transfer of information, they must be working on the assumption that information CAN be transferred via quantum entanglement.

So I don't think that it can be as clear cut as all that.
People don't pay for that kind of research, when there's no possible prospect of success.

This is why I usually block your posts, MM. You read things, the information in what you read simply does not penetrate, yet you spout your misunderstanding as fact regardless!

Yes, quantum entanglement is utilised in quantum computing. BUT NO NO NO NO NO! This does not involve in any way the transfer of information faster than the speed of light!

It is simply a (so far theoretical at any but the most minute scales) method of performing certain calculations far faster than they can be performed using traditional computing methods. The trade-off being an inherent probability of the result being incorrect.

And your quote refers to experimental proofs of quantum entanglement. It has nothing to do with faster than light transfer of useful information.

You have managed to be even more wrong than rEv in a far shorter time.

[JimC]

You are all getting cranky. Take a break, have a wank and drink some gin...

[mistermack]

Xamonas, there's something wrong with you.
You seem to blame me for upsetting you, yet all you ever post is aggressive shite like that.
What do you expect? I only reply in kind, I've never instigated any unpleasant exchange with you.

I'm not going to reply to that shite, except to say that it comes out of your arse, no link, no verification. Your usual shitty standard.

A quantum computer utilises quantum entanglement. Whether the result is probabilistic vs deterministic is irrelevant to the point in discussion here. You're reasoning is flawed, XC. You are trying to use quantum computing to deny that quantum entanglement involves the transfer of information instantaneously. The reason I brought up quantum computing is that it's a case of information being utilised from the phenomenon of quantum entanglement. That is undeniably true. Whether that information is transferred instantaneously is another matter, and one that MiM has tried to address, but I'd suggest that like most of us (including myself), he doesn't actually understand what's going on. From a relativistic macro perspective, that information IS transferred instantly. Experiments have verified this, as both I and MiM have said. The argument seems to be that on a quantum scale, notions of cause and effect become blurred and there is no coherent way to talk about simultaneity. I don't know if this is true or not, but the general weirdness of that concept would at least be at home with all the other weirdness of QM.
