"ONLY" is a tricky word. For example Giles Brassard has published
some work on "Quantum Cryptography" where security depends on
principles of quantum physics.

One reference is "An Update on Quantum Cryptography", by
Charles H. Bennet & Giles Brassard, pages 475-480,
"Advances in Cryptology: Proceedings of Crypto 84",
Springer Verlag Lecture Notes in Computer Science #196.
