Quantum cryptography effectively ‘useless’
“The basic idea is still unbelievably cool, in theory, and nearly useless in real life,” he said.
“Even quantum cryptography does not ’solve’ all of cryptography. The keys are exchanged with photons, but a conventional mathematical algorithm takes over for the actual encryption.”
Schneier explained that the weakest point of any network is not in the transmission of data itself but at the endpoints of the network. Quantum cryptography does not solve this basic problem.
