quantum entanglement real world applicationphysicsweb sent me an article a while back about successfully using two entangled photons as a sort of encryption key for a banking transaction. I understand the spin-state dependence from one to the other, but I don't understand the nature of the crystal that they used to produce the entangled pair, and was hoping someone could enlighten me.

Re: quantum entanglement real world applicationDid you also hear about Vlatko Vedral attributing mass to quantum entanglement? "Physics is like sex. Sure, it may give some practical results, but that's not why we do it." - R. Feynman "Yet if there really is a complete unified theory, it would also presumably determine our actions. And so the theory itself would determine the outcome of our search for it!" (Stephen Hawking, A Brief History of Time, p13) Offline #3 2004-11-06 21:36:40Re: quantum entanglement real world applicationThe entire idea behind the Higgs field sounds a lot like the concept behind aether. I guess time will tell. Chemists are physicists who don't do math.

I'm not sure what type of crystal they used. One of the most popular is LitO3. Chemists are physicists who don't do math.
