Are we on the cusp of a revolution in quantum computing? What does it mean for security and cryptography? And will it get us closer to a general artificial intelligence? Lily and Gordon chat to Professor Elham Kashefi - quantum computing professor at the University of Edinburgh - to find out all of this and more.

Elham is the Personal Chair in Quantum Computing at the School of Informatics University of Edinburgh and also the co-founder of VeriQloud.
