Fortunately there do appear to be some non-military applications. As the writeup says, it can turn some gases directly to plasma. This technology can be further applied to the cheaper production of plasma televisions, possibly very large ones.
Well, yes, although you have overlooked the primary benefits that a quantum encryption scheme would offer: quantum entanglements, and not needing to be concerned that a quantum computer could break a non-quantum-but-NP-hard problem.
Re the implementation query you have, I think that philosphically, an algorithm cannot be separated from its implementation.
People often find small, insignificant reasons to criticize those of greater abilities. I wonder that you can't find satisfaction in something more substantial.
But this is not the place to discuss it; I just pity you for your small mindedness. The world is an exciting place, dont spend your life picking through the details.
Light travels at a constant speed c; that's true no matter how fast or in what direction the observer is going. So no, they didnt mean that light had slowed down, although its hard for the layman to see why. Look to wikipedia for a good explanation.
I suspect they mean 120km/h, because of repeaters along the fibre must be more complex than usual for this application.
Quantum "encryption" is no better (or worse) than regular encryption. a simple oversight in the implementation can render you're algorithm
breakable.
In my coursework classes I am taking for my PhD, we looked in-depth at the breaking of the enigma code, and these techniques are general: they apply to any code. The germans thought that by adding an extra rotor they were safe, and here we see history repeating itself. NO YOU ARE NOT SAFE BECAUSE YOU ARE USING PHOTONS! Start from the premise, "my message will be hacked" and work from there, it is the safest rout.
