In quantum cryptography we use quantum
mechanical effects to construct secure protocols. The paradoxical
nature of quantum mechanics allows for constructions that solve
problems known to be impossible without quantum mechanics. This lecture
gives an introduction into this fascinating area.
Possible topics include:
You need no prior knowledge of quantum mechanics. You should have heard some introductory lecture on cryptography. You should enjoy math and have a sound understanding of linear algebra.
[NC00] Nielsen, Chuang. "Quantum Computation and Quantum Information" Cambridge University Press, 2000. A standard textbook on quantum information and quantum computing. Also contains some quantum cryptography.
