DESCRIPTION

Quantum information science has the potential to revolutionize information processing, in the form of dramatically faster quantum algorithms and novel protocols for cryptography, metrology, and sensing. The Quantum and Linear-Optical Computation group explores the features of quantum theory that enable advantage in quantum information processing tasks, in particular those present in photonic implementations of quantum computers. There is not a single way to harness these quantum effects, so studying different models of quantum computation enables us to pinpoint different ways to get quantum systems to work their magic.
Our group has been recently established, please note the following opportunities:

  • If you have a Master’s degree and would like to join as a PhD student, please consider applying to the 2nd round of the Quantum Portugal Initiative PhD scholarships: https://inl.int/quantum-portugal-initiative/
  • If you are an experienced researcher in the field, there is a Staff Researcher, tenure-track position open, with application deadline on November 21st, 2019: http://careers.inl.int/our-vacancies/

Multimode interferometers are a special type of photonic quantum computer.

RESEARCH PROJECTS

  • Resources for quantum computational speed-up in topological, measurement-based, and circuit-based quantum computation.
  • Experimentally-friendly characterization of multi-photon indistinguishability
  • Quantum computation with integrated photonic chips
  • Classical analogues of quantum non-separability and contextuality
