:::perhaps we should just change verb tenses to remove these citation needed tags, since it seems the state of current research is not at the point indicated? see my recent edit for an example. changed "is used" to "could be used".

== Post-quantum cryptography ==
I have modified the entry about post-quantum cryptography. It was giving the impression that quantum cryptopgraphy could be broken by a quantum computer, which is of course not the case. The aim of post-quantum cryptography, in this usage of the term at least, is to find alternative _classical_ methods that are presumably secure against quantum computers. Quantum cryptography is obviously secure against adversaries with quantum computers, since those cannot violate the laws of quantum mechanics that are used to prove the security of QC.
