"Cryptographic key communication can be guaranteed absolutely secure, even over completely unsecured lines."
Hits me like anything, but it looks like its practically possible (though with some practical limitations that needs to be overcome) with quantum physics.

Personally to me this doesn't mean end of mathmatical cryptography. As this looks like half of the security, just securing data communication. I am not aware of any usage of this priniciple for securing stored data. I believe this one should also have overhead as we do have in asymm crypto but more secure than that. Hopefully this could be useful for securing communication of symm keys. I am sure first practical install will be a "secure proton tunnel" between Pentagon and WhiteHouse or Camp David.
