There is little doubt that the advent of the computer has had one of the most far-reaching impacts of any invention in the history of mankind. These days, it’s difficult for most of us to imagine life without them. But building ever faster processors is becoming something of a challenge.

In this episode I speak to Prof Winfried Hensinger, director of the Sussex Centre for Quantum Technologies.

We talk about his work on creating the world’s first large-scale quantum computer, how it works, and how quantum computers could help scientists do everything from breaking complex forms of encryption to creating innovative new medicines.
