Welcome to our group website

We are working in quantum technologies with a focus in implementations of quantum computation and quantum simulation with quantum optical systems. Our research could be applied towards developing exotic high-performance quantum processors and simulators, and also for fundamental science in the area of strongly correlated quantum systems. read more.

Jan 2022:  Arthur Strauss, from EPFL is joining us this month as a PhD student! Welcome Arthur!
Aug 2021:  Chee passed his qualifying exam! Congrats! We also have a new PhD student, Harvey from Imperial College London joining us this month! Welcome Harvey!
July 2021:  Beng Yee, passed his qualifying exam and also put his first paper on the arXiv on quantum machine learning with linear photonics! Another paper on persistent homology is also up on arXiv!
June 2021:  Dimitris was invited to speak on the VI ICQT 2021 held virtually in Russia along many of the world leaders in the field. He also talked at the European Dialogue on Internet Governance (EuroDig).
May 2021: Two of our pre-print works are published ! (1) First one on probing quantum phases of matter with quantum supremacy signatures is published in Physical Review B (2) Second work on qubit-efficient encoding schemes for binary optimisation problems is published in Quantum.
April 2021: Dimitris was invited to speak at TUC the World Quantum Day. The World Quantum Day is an initiative from quantum scientists from 65+ countries, Dimitris representing Greece, and was launched on 14 April 2021. The video of his talk with title “Από την Κβαντική Φυσική στους Κβαντικούς Υπολογιστές” in Greek is available online.
