Marco Tomamichel Group

Theory

Marco Tomamichel holds a joint appointment as CQT Principal Investigator and Professor in the Department of Electrical and Computer Engineering, National University of Singapore. His research interests lie in the intersection of information theory, cryptography and quantum mechanics.

Marco received an MSc in Electrical Engineering and Information Technology from ETH Zurich in 2007. He followed his interest in quantum information to graduate with a PhD in Physics at the Institute of Theoretical Physics, also at ETH, in 2012. He came to CQT for a postdoctoral stint, then was a Research Fellow at the University of Sydney and an Associate Professor at the University of Technology Sydney before returning to NUS in 2020.

Marco Tomamichel Group

Our research explores the intersection of information theory, cryptography and quantum mechanics. Our focus is the mathematical foundations of quantum information theory, for example the study of entropy and other information measures, as well as theoretical questions that arise in quantum communication and cryptography when the available resources are limited.

Information processing with finite resources: One main challenge when engineering quantum processors is that complex quantum systems are notoriously hard to prepare and control coherently. We therefore investigate quantum information processing with noisy and limited resources.

Mathematical foundations of quantum information: Progress in information theory often goes hand in hand with a more thorough understanding of the mathematical framework underlying it. We are interested, for example, in exploring various measures of entropy, information and correlation based on Rényi divergences.

Cryptography in a quantum world: Securing information against potential adversaries is a ubiquitous challenge in our modern world. We are interested in security proofs for various cryptographic schemes.
