The MQV Colloquia feature interdisciplinary talks given by local as well as invited international experts. The colloquia, which are accessible to a worldwide audience via videoconference, cover all aspects of quantum technologies, with a focus on MQV research activities. The goal of the series is to establish and strengthen connections with quantum-technology experts worldwide and to provide a platform for education and scientific exchange for and with the local quantum ecosystem.
"The State of Factoring on Quantum Computers"
Dennis Willsch – FZJ
Abstract
The problem of factoring integers plays a key role in data and communication security. Quantum computers promise a breakthrough in solving this problem. However, current devices cannot live up to the promise. We discuss (1) fundamental challenges on digital quantum computers and (2) experimental evidence for limited scalability on analog quantum computers. We also scrutinize the most recent factoring records. We conclude with future perspectives on factoring large integers on quantum computers.
Short bio
Dennis Willsch was born in Cologne, Germany. He received his PhD degree in physics from RWTH Aachen University in 2020 for simulating the time evolution of transmon quantum computers on digital supercomputers. He is a senior researcher in the Quantum Information Processing group at Jülich Supercomputing Centre, Forschungszentrum Jülich. His current research interests include modeling quantum technology experiments, benchmarking existing quantum computers and quantum annealers, and simulating the time evolution of quantum information processors on supercomputers.
