We are a research group at the Centre of Quantum Technologies and the Department of Electrical and Computer Engineering at the National University of Singapore.
- Investigating quantum information processing with noisy and limited resources
- Analysing the fundamental limits that restrict information transmission between two parties that possess a small quantum device
- Devising security proofs for cryptographic schemes
- Exploring measures of entropy, information and correlation based on Rényi divergences
Background
Our research interests lie in the intersection of information theory, computer science and quantum physics. The main focus is on the mathematical foundations of the theory of quantum information, for example the study of entropy and other information measures and their applications. A particular application area of our research are theoretical questions that arise in quantum communication and cryptography when the available resources are limited.
Miscellany
The methods developed for quantum information theory have found applications in other areas of physics, engineering and computer science. For example, our methods are useful to analyse entanglement and more general resource theories in physics. We are also interested in establishing lower bounds for various problems in quantum learning theory.
