Addictive Science Posted December 28, 2013 Posted December 28, 2013 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
ajb Posted December 28, 2013 Posted December 28, 2013 You cannot transmit information faster than the speed of light using entanglement.
Addictive Science Posted December 28, 2013 Author Posted December 28, 2013 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.
swansont Posted December 29, 2013 Posted December 29, 2013 How is entanglement going to give you a better system than simple observation?
Addictive Science Posted December 29, 2013 Author Posted December 29, 2013 Time delay between event and arrival transmission would be almost instantaneous. Compared to 8min+/- light travel transmission from Sun to Earth.
Popcorn Sutton Posted December 29, 2013 Posted December 29, 2013 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.
swansont Posted December 29, 2013 Posted December 29, 2013 Time delay between event and arrival transmission would be almost instantaneous. Compared to 8min+/- light travel transmission from Sun to Earth. No, it would not. Entanglement does not allow for superluminal communication.
Enthalpy Posted December 29, 2013 Posted December 29, 2013 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.
Popcorn Sutton Posted December 29, 2013 Posted December 29, 2013 No, it would not. Entanglement does not allow for superluminal communication. So entangled interactions don't occur faster than the speed of light?
Strange Posted December 29, 2013 Posted December 29, 2013 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.
Popcorn Sutton Posted December 29, 2013 Posted December 29, 2013 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.
imatfaal Posted December 29, 2013 Posted December 29, 2013 It is not clear there is a speed associated with them. And they certainly cannot be used to communicate information anyway. 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. 2
Daedalus Posted December 29, 2013 Posted December 29, 2013 (edited) 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 Edited December 29, 2013 by Daedalus
swansont Posted December 29, 2013 Posted December 29, 2013 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.
Popcorn Sutton Posted December 29, 2013 Posted December 29, 2013 The limit of c sounds like a rule to me -.-
Daedalus Posted December 30, 2013 Posted December 30, 2013 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. I see. Thanks for the correction.
Sensei Posted December 30, 2013 Posted December 30, 2013 The limit of c sounds like a rule to me -.- It's experimental evidence. And it's half century older than quantum physics. http://en.wikipedia.org/wiki/Fizeau-Foucault_apparatus If you don't agree, build device showing it's possible to exceed speed of light.
hypervalent_iodine Posted December 30, 2013 Posted December 30, 2013 ! Moderator Note Popcorn, please avoiding posts that consist solely of videos or links to other sites, especially when those videos are as long as the ones you've posted. If you have something to say in response to the OP, please do summarise your points in written form; it is a little much to expect people to trawl through hours of footage to figure out what you're trying to say. You may provide a link to your YouTube videos as a supplementary to that if you wish, but do not make them the entirety of your post.
Enthalpy Posted December 30, 2013 Posted December 30, 2013 So entangled interactions don't occur faster than the speed of light? Acting on one particle does not modify the properties of the other, hence no information transfer.
Strange Posted December 30, 2013 Posted December 30, 2013 I don't agree with that. If you can approximate (determine the environment) of n points in time, then you have information. Huh?
swansont Posted December 30, 2013 Posted December 30, 2013 The limit of c sounds like a rule to me -.- Yes, it is a rule.
Popcorn Sutton Posted December 30, 2013 Posted December 30, 2013 So what you're saying is that quantum entanglement doesn't exist?
Strange Posted December 30, 2013 Posted December 30, 2013 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.
swansont Posted December 30, 2013 Posted December 30, 2013 So what you're saying is that quantum entanglement doesn't exist? Yes, it exists. It just doesn't work the way you seem to think it works.
