So with current technology it is unhackable...Im sure wireless internet was thought impossible at one time also. My point was, I dont like people who say things like this are impossible, when in reality it will just take some time and money.
It is not a matter of technology it would be a matter of changing our understaning of the fundamental laws of nature and physics. You cannot view the state of a photon without changing the state of that photon. It can't be done. If you want we can get into the mathmatics behind it, but I barely understand a lot of it, so I don't think I can do it justice and it requires a pretty good knowledge of higher level calculus. Suffice it to say that it is not a matter of finding some neat new technology, it would require a monumental change in our understanding of the universe similiar to what Einstein and Newton did. Is it possible that our understanding could change this much? Yes, but I doubt it will happen. We actually understand the behavior of light, specifically photons, pretty well. The changes in our understanding of physics and the laws of nature will be in the weak force, the strong force, the eletromagnetic and gravitional forces and how those forces interact. That is where most research into quantum mechanics and string theory is taking us today.

Like I said, it could happen, but most of the leading physicists in the world don't know how it would be possible. I only say it is possible because most of the physics behind this type of encryption is just theory with no practical way of confirming a lot of this. Our understanding and the mathmatics behind quantum physics is way ahead of what we can practical test. So what we know could definitely change.

Although, this claim that it can't be broken isn't marketting hype dreamed up by a ad guy that has no understanding of the technology. So it is a lot different than the CEO of Oracle saying his product is unbreakable.

One time pads can be broken, IF you want to spend 10-12 years working on one
Yes they could. But in quantum encryption if it is detected that someone else is listening in on the conversation the one time pad is recalculated and the data is resent. This will continue to happen until the transfer of data takes place with no one else listening into the conversation. If you can only detect one photon of the transfer before the keys changes you have no possibility of ever determining the entire key, or even what the encrypted data is.
