Title:

Quantum Cryptography

Abstract:

Cryptographers have the difficult job of understanding and imposing limitations on adversarial behaviour. By incorporating the unique features of quantum physics, cryptographers can benefit from one of quantum physics’ fundamental properties: the “quantum no-cloning theorem”. This is one of the simplest yet most profound results in quantum information. According to this theorem, it is not possible to perfectly copy an unknown quantum state.

In this tutorial, we will discuss some of the amazing consequences of this theorem, such as unforgeable quantum money, perfectly secure quantum communications and certified deletion.
