Computer Science Department Colloquium: Quantum Uncloneability and Quantum Protocols

Abstract: 

The “quantum no-cloning theorem” 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 presentation, we will introduce the formalism that leads to quantum information and to the no-cloning theorem and we will discuss some of the amazing consequences of this theorem, such as unforgeable quantum money and perfectly secure quantum communications. As a second related topic, we will discuss the availability of cloud quantum computing infrastructures and how to achieve privacy and verifiability in this scenario.
