erik2000 Because humans are pretty primitive primates, mostly driven by fear and instincts. Mankind will certainly exist in 1000 years, the question is, if civilization will still exist or if we fall back to living like in the middle ages ? Fact is: a) many people in industrialized states are afraid of any kind of technology and glamorize the "primitive life" of former times. An increasingly number of idiots even actively reject science (anti-vaxxers, homeopaths etc). b) there are a lot of religious nuts on this planets (roughly 80% of all humans on this planet believe in some kind of invisibly sky wizard, instead of science), c) we still haven't developed a technology for conserving knowledge over longer times. The one that comes closest is written books. Everything digital needs to be copied repeatedly to not get lost. (E.g. NASA lost a lot of it's information about the Saturn V stored on tape - we couldn't rebuild this thing, even if we wanted to. We would have to engineer it anew). d) We have depleated pratically all easily accessible sources of resuorces. So once technology gets lost/is gone, we won't have the technology anymore to exploit the remaining resources and are thus stuck and couldn't rebuild civilization, even if we would still knew how to do it.

Question about photon transmission maintaining quantum states. Speed of light changes when not in a vacuum because the photon is bouncing around between air molecules and whatnot. These interactions are determined by the Feynman diagrams, right? So how can you transmit a photon through any kind of medium (glass, air, anything) and have it be the same photon at the other end? Wouldn't that limit the possible Feynman diagram interactions and thus change the energy of those interactions? Wouldn't the fact that you know that you got the same photon out of the interaction than you sent in force the possibilities that a new photon was created by some convoluted diagram (where the photon split into an electron/positron pair, then re-combined to a photon) to zero? Or would the quantum state of the original photon be passed to all those possible quantum states and thus always be preserved in the outgoing photon? But if that's the case, how was the entanglement preserved?

[@93musman]

Light slowing down is not due to bouncing between the atoms of environment, best explained in this video kzbin.info/www/bejne/eYbNpWZsiKlmnpo

[@KohuGaly]

strictly speaking, when photon enters non-vacuum medium it spawns a new particle, called polariton. They are a combination of the original photon and all of its interactions with the medium. Also, they have mass - that's why the speed of light is lower there. The key point here is, not all interactions cause de-coherence. For example you can bounce a photon off a mirror. It technically is an interaction. Yet all properties of the photon are perfectly preserved, except its momentum perpendicular to the mirror is flipped.

[@faaltoh]

The way I understand it is that no interactions occur in the medium. If that was the case then the photon simply would not arrive at the detector. If the medium is concrete then you have your "Feynman diagram interactions" when the photon hits the concrete. If the medium is fiber optics then the interaction is at the detector at the far end. You seem to have your physics a bit messed up.

On average ECC just implements the DLP or factorization problem of DH or RSA, just in a different way so that the required key length is shorter.

@Albert Jackinson Im just going to go off memory but iirc classic encryption could be quickly cracked by a quantum computer however bruteforcing wouldnt go away with quantum encryption so to counter act that your software for encryption would need a quantum key thats state constantly changes in hopes that the interval between changes couldnt be cracked before the change.
