Open positions

I am looking for PhD students and postdocs for my new group at the Department of Electrical and Computer Engineering (ECE) and the Centre for Quantum Technologies (CQT) at the National University of Singapore (NUS). My group will be part of the vibrant international research community around CQT. Topics of interest include quantum Shannon theory and statistics, resource theories, quantum cryptography and other technical/mathematical aspects of quantum information. This is an open-ended call and I will consider high-quality applications as they come in.

Please contact me at marco.tomamichel@nus.edu.sg for further information.

  • CQT PhD program: I am looking for Physics, Computer Science or Mathematics graduates with strong interest in the mathematical aspects of quantum information, and the skills required to pursue technical questions in quantum Shannon theory and cryptography. The CQT PhD program offers generous funding and great flexibility to its students. More information can be found here: https://www.quantumlah.org/students.
  • ECE PhD program: I am looking for Engineering graduates with background in either information theory or cryptography and a keen interest in the intersection between engineering and quantum information. This degree has a significant coursework component. More information can be found here: http://www.eng.nus.edu.sg/graduate/graduate-research-based-programmes/ph-d-master-of-engineering/
  • Postdoctoral research fellowships: I am particularly looking for researchers with a strong track-record working on technical aspects of quantum Shannon theory and cryptography, but strong candidates with proven expertise in other aspects of quantum information are also encouraged to apply. Successful applicants will be granted significant independence concerning their research focus and receive generous travel funding. They will be expected to contribute to the group, for example by co-supervising student projects. Positions will initially be offered for two years, with the option to extend.

Research portfolio

Our research interests lie in the intersection of information theory, cryptography and quantum mechanics. The main focus is on 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. Consequently, there will be limitations on the size and noise resilience of quantum computers for the foreseeable future. We therefore investigate quantum information processing with noisy and limited resources. For example, we want to understand the fundamental limits that restrict information transmission between two parties that possess a small quantum device.

Mathematical foundations of quantum information

New results on mathematical properties of information and correlation measures often have various applications beyond the specific ones that originally inspired the research. As such, progress in information theory often goes hand in hand with a more thorough understanding of the mathematical framework underlying it. For example, we are interested 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, appearing in diverse guises such as sending private email and online commerce, among myriad others. Quantum cryptography studies secure information processing using quantum devices. We are interested in security proofs for various cryptographic schemes—formal mathematical arguments that certify that the behavior of a given protocol is indeed secure.

Marco Tomamichel
Principal Investigator

I am an Associate Professor with the Department of Electrical and Computer Engineering (Block E4, Level 7, Room 5, 4 Engineering Drive 3, Singapore 117583) as well as the Centre for Quantum Technologies at the National University of Singapore (NUS). ​I am one of the founding editors of Quantum and an Associate Editor for the IEEE Transactions on Information Theory.

I obtained a Master of Science degree from the Department of Electrical Engineering and Information Technology at ETH Zurich, and a doctorate in Theoretical Physics also from ETH Zurich. Before starting my current position I was a postdoc at the Centre for Quantum Technologies, a University of Sydney Postdoctoral Fellow and Australian Research Council Discovery Early Career Researcher Award fellow and Associate Professor at the University of Technology Sydney (UTS). 

My full CV is available here and my publications can be viewed on Google Scholar or arXiv. My ORCID number is 0000-0001-5410-3329.
