An Idea came to mind a few weeks back and I'v had some time to mull it over, but I'm on the fence as to whether or not I think it could work. I was thinking of a way we could predict and transmit and instantaneous signal of when a solar flare is about to go off and or has gone off. I found an Article Here that describes a way to possibly predict when a flare is about to go off and use as a preemptive detector. Then I was thinking, well that's good and all, but how can we transmit that information faster than the speed at witch it will travel to Earth at (10.43 million and 12.75 million kilometers per hour). Not sure how long that would actually take to reach us, but it wold be a measurement of how long we'd have to prepare. Namely, with faster that Light Speed or Radio Wave Transmissions you'd be able to attain Maximal time to prepare for a Solar flare event.

This brings me to where I think we could capitalize on a use for Quantum Entanglement (QE). With new developments from NASA and other labs around the world, this could be a perfect application for applying this technology.

ex: Solar Flare Detector +Satellite Probe + Entanglement - Assisted Communications System = Instantaneous Preemptive Solar Flare Detection; I Think? If I have missed something in translation or have looked over a step let me know. Thanks

You cannot transmit information faster than the speed of light using entanglement.

I was thinking more of a basic detection system. Where in the information is not transferred, but and alarm is triggered telling an entangled partial/particles positioned on a satellite and one on Earth could respond to one another. In this case they would simply say that something is about to happen or has happened based on a detector and Trigger that would alter the positions of the entangled particle/particles. Almost binary I/0 depending on what is being detected and by what detector your reading.

How is entanglement going to give you a better system than simple observation?

Time delay between event and arrival transmission would be almost instantaneous. Compared to 8min+/- light travel transmission from Sun to Earth.

How do we measure the entanglement to predict these occurrences? There has to be a numerical value and a probe of some sort I'd assume.

No, it would not. Entanglement does not allow for superluminal communication.

In addition to entanglement transporting no information:

- Light and radiowaves propagate much faster than the plasma emitted by a flare, so observing or transmitting with normal means suffice

- Who cares about Solar flares? The proper response is not to detect it and disconnect the power lines, but to put protective components at the power lines. This is done for decades, and since then no blackout resulted from a Solar flare.

No, it would not. Entanglement does not allow for superluminal communication.

So entangled interactions don't occur faster than the speed of light?

It is not clear there is a speed associated with them. And they certainly cannot be used to communicate information anyway.

I don't agree with that. If you can approximate (determine the environment) of n points in time, then you have information.

With a method of passing polarized photons from Alice to Bob and two entangled photons (set in a bell state by Alice and one or other sent to Bob prior decision of message) Alice can then communicate 2 classical bits of information to Bob by acting on her photon and then transmitting it to Bob. She has in essence communicated two classical bits of information by sending one qubit of information - note that although Alice sends two photons in total only one of them is sent after the message is decided. Two classical bits of information in one qubit is the passing of information via entanglement.

 

The transmission would be at the speed of light in the fibre optic or what ever else was used.

From what I understand, when you measure an entangled property, you end up destroying the entanglement. If that is true, then it wouldn't matter if you could send information faster than the speed of light with an entangled system. The device located near the sun would signal the device on the Earth. However, you have to know when to check for information coming in. The device on Earth would be constantly measuring the entangled state. Thus destroying the entanglement upon the first check rendering it useless. Of course, I could be wrong

You don't know the state of the entangled particle until you measure it. The only way to communicate your measurement is via a classical channel, limited to c.

The limit of c sounds like a rule to me -.-

I see. Thanks for the correction.

It's experimental evidence.

And it's half century older than quantum physics.

If you don't agree, build device showing it's possible to exceed speed of light.

Acting on one particle does not modify the properties of the other, hence no information transfer.

I don't agree with that. If you can approximate (determine the environment) of n points in time, then you have information.

 

Huh?

Yes, it is a rule.

So what you're saying is that quantum entanglement doesn't exist?

Entanglement exists. But it cannot be used to communicate information faster than light.

Yes, it exists. It just doesn't work the way you seem to think it works.
