I see. So more specifically, is it possible to contain the D description of the D+1 system within the D+1 system it's describing? I'm trying to get at the implications to the simulation argument. Can a complete description of the universe be contained within the universe? Or, I guess more...

I'm getting a rough idea of the holographic principle relating the shannon entropy of a boundary surface to the thermodynamic entropy contained within the bounded volume. So far as I understand the primary claim is that the total information needed to describe the entirety of the internal...

Interesting. Would you mind linking the sources for that?

I have, and that's actually what I was referencing but I may have worded it poorly. In the train paradox, the difference in simultaneity is due to the fact that c is constant relative to each observer. So in S (ground observer) for the case of the ships, both ships move equally and light...

So does the speed of light and observation hold the explanation to this? What I'm thinking is that from frame S, both ships can be seen moving simultaneously because they are equally distance from an observer in S, thus light reaches the observer equally. But in S', each ship will observe a...

http://en.wikipedia.org/wiki/Bell%27s_spaceship_paradox#Importance_of_length_contraction In Bell's spaceship paradox, the spaceships appear to maintain distance from one another from inertial frame S. Got it. But because of length contraction within each rigid body, when observed from the...

I'd have to agree. But this is the purpose of this thread: I'm trying to come to terms with a claim I've heard repeated, and is obviously a difficult one to just follow along with without fully wrestling with it. That said, thanks to everyone for your responses. One difficulty here may be...

Again I'll have you look at the attached image. Continuing my model of a sphere having any possible orientation when entering a measuring apparatus. M1 and M2 are the points of measurement, 120° apart. θ can be at any value, and given a value for θ, the probability of M2 matching is equal to...

Thanks for the responses. But so far these answers are of the "just because" form. I am familiar with the theorem. Indeed, DrChinese, I've ready your own write-ups on both Bell and EPR in the past and found them helpful. But perhaps the central question was missed. The theorem is predicated...

I know Bell has been discussed ad nauseam on these forums, but there's something I'm having trouble coming to terms with: the wording and usage of Bell's theorem seems to be near-sighted. "No physical theory of local hidden variables can ever reproduce all of the predictions of quantum...

Thanks Dali, For some reason I was missing the fact that the shared information is only about the chosen basis of each party, not the resulting 1/0 associated. So that definitely clears that up thank you!

Thanks Jedi that was really informative. And thanks ppnl that verifies what I thought. The point I'm making is that the quantum encryption, at the end of the day, is only as effective as the encryption for the classical channel. In order for Alice and Bob to compare their quantum analyses...

I've read that article thoroughly, and as I mentioned before I understand quantum key distribution (which is all that article talks about). But look at the "Man-In-The-Middle" Attack section to see what I mean. The only way to actually be secure is to use a shared key like an OTP to...

I'm finding it absurdly difficult to get detailed information about the exact methods of transmitting quantum encrypted messages. I have a working understanding of quantum mechanics but I'm not a computer scientist. The most I can find is descriptions of QKD which use a quantum channel as well...

Ken, I'm going to have to disagree. Wave-particle duality is not a unification. They are not always the same thing. Indeed they are never the same thing simultaneously. As it was discussed earlier we know that on the fundamental level photons are not waves, they are particles. But they...
