Quantum Communication and Cryptography

Quantum Information Processing has the potential to revolutionise the future of information and communication technologies. Our long-term vision is a network of quantum and classical devices, where individual agents have the ability to communicate efficiently in a variety of ways with trusted and untrusted parties and securely delegate computational tasks to a number of untrusted large-scale quantum computing servers.
In this talk, I will describe some fundamental results in quantum cryptography, including the existence of unconditionally secure key distribution and the optimal quantum protocols for coin flipping and bit commitment. In addition, I will show examples where quantum communication can be exponentially more efficient than classical communication and also, how the study of quantum communication can bring new insight in the study of classical information.
No previous knowledge of quantum information is needed.
