Current Research

  • Professor A Ekert is one of the world's leading authorities in quantum information science, in particular in quantum cryptography. He is the founding Director of the Centre for Quantum Technologies (CQT) at NUS, established as Singapore's first Research Centre of Excellence in December 2007. He had previously led the Quantum Information Technology group in NUS, which formed the core of the new centre. He has enriched the intellectual environment of the University, attracting outstanding physicists and computer scientists to collaborate with Singapore-based researchers and to join CQT. As of 2012, CQT has more than 200 staff and students.

  • His research extends over most aspects of information processing in quantum-mechanical systems, with a focus on quantum cryptography and quantum computation. It is a cross-disciplinary field bringing together theoretical and experimental quantum physics, mathematics, logic, computer science and information theory. His work is mostly theoretical but its results also bear directly on issues of experimental implementation. One reason why it has attracted attention from industry and government agencies is that quantum cryptography can guarantee perfectly secure communication. Another is that projected quantum computers will be capable of efficiently solving some problems for which there is believed to be no efficient classical algorithm.
