ML4Q&A - from the lives of quantum physicists   /     11. How David DiVincenzo got into quantum computing

Description

In this episode, we talk to David DiVincenzo, Director of the Institute of Theoretical Nanoelectronics at Forschungszentrum Jülich & co-founder of the Institute for Quantum Information which is a joint institute of RWTH Aachen and the Forschungszentrum. We start by listening to David's take on different aspects of the fast developments in the field of quantum computing. Then, we take a deep dive into the mid eighties and early ninties and discuss how David started working on quantum computing before Shor’s algorithm and quantum error correction were discovered. Naturally then, him and his collaborators at IBM were ready to contribute to the developing field. We touch upon the DiVincenzo criteria and the Loss-DiVincenzo quantum dot proposal and get to know some of the mentors David was lucky to have had.
