Entanglement Definition and 870 Threads

Hey, folks. A pretty light read on how quantum entanglement works, starting from first principles without using math but with lots of pictures. Quite good! http://www.joot.com/dave/writings/articles/entanglement/ Ciao! T

For more than 70 years, QM advocates have misrepresented Einstein's EPR work. Once it becomes clear what Einstein was really saying, it should be very difficult to stick with Bohr's bizarre interpretation of entanglement. Among the FEATURE ARTICLES (Cover Story) of the Scientific American...

So silly question! but how does EPR and entanglement theory are related? I mean the history and its cocepts of similarities. Thanks in advance. Somy :smile:

is it possible to move the quantum state of individual atoms from one location to another using the principal of quantuam entanglement

What is quantum entanglement? why is it "spooky"

Hi All, I just came across a paragraph in a little book called "Entanglement" by Amir Aczel. In it it said that Wayne Myrvold proved that it is undecidable whether two states are entangled or not. Does anyone have any knowledge or references to his ideas? Thanks, Jurgen

Hello I would be interrested in good (web) references dealing with "entanglement measures". I am looking for not too mathematical references. I would like to see the connections with physics more than with quantum information theory. I would be interrested to see the concepts applied to...

Hi everybody, For the ones interested by a hidden variable model of EPR state with a hidden communication channel , I recommend the last Cerf, Gisisn Massar and Popescu quant-ph/0410027 paper (4 pages – a short concise one). I think it is a good one (with the pointers it gives). It...

My question is in the title please do your best to put this into terms that a novice could understand. I sure am no expert :) Thanx

I'm trying to understand why entanglement is said to be "spooky." The model I have is that 2 entangled particles are related, such that they have identical states when measured. The entanglement process is what ensures they have identical states. So it's no surprise they measure out the same...

Please explain what's entanglement distillation and what's entanglement concentration. I'm mistaken to think that these two techniques are related somehow?

This is probably not the best site to get scientific information from, but still: http://computer.howstuffworks.com/quantum-computer1.htm I don't understand the final bit - how does entanglement allow scientists to know the value of the qubits? I can understand how it could allow them to...

Can quantum entanglement effect be explained by a carrier particle traveling along spacetime geodesics with a zero time component? Or perhaps traveling along normal geodesics and then falling back in time along a time-like curve? Either of these essentially forms inifinite-speed motion of the...

What I say or do here and now can affect someone somewhere sometime, is this the same as quantum entanglement? If no one doesn't say or does here and now then nothing will ever happen in the future. Someone can only do or say something only if he or she is alive. But what someone does or says...

Quantum entanglement, if I understand it correctly, specifies the phenomenon where the scattered pieces of a particle somehow know the whereabouts of its other pieces. Does that mean that by taking a neutron from atom A and placing it away from atom A, the atom would know where the missing...

First post. There's something I don't quite understand about quantum entanglement and I'm hoping someone here can put me right. When I first heard about the Aspect experiment, I thought that it had to open the way forward for faster-than-light information transfer as follows: Bob is on...

I would like your comments on whether a model of EPR entanglement based on superstring theory makes any sense. Let's suppose we are concerned with understanding the entanglement of an electron/positron particle pair created at a point in an EPR experiment. The particles fly off in opposite...

OK, I would really appreciate it if somebody could explain to me as simply as possible why entanglement happens (between electrons), what a Cooper pair is, and what causes superconductivity. I have read that if two electrons are entangled and something happens to one of them, it will affect...

Are virtual particles entangled when they appear? If so then when one of the pair falls into a black hole and other flies off, do they remain entangled? If so, does this mean that by observing black hole radiation we can in principle 'see inside'?

I have a question. Is there anybody helping me explain this inequality or if you can prove it . Thanks
