I stopped reading at "quantum cryptography is used to secure Swiss bank transactions". The highest conceivable levels of finance are protected using nothing more exotic than SSL/TLS. I'm sure there's an awesome paper buried somewhere in this story, but I'm equally sure this reporter has no idea what it means.
Scroll up a bit, by the looks of the comments it seems like it's another case of "clueless journalist makes a hokey-sounding story about a real technology".
This is why I don't generally ever read online articles about technology written by 'normal' news outlets.
