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.

March 2020: Our work on “Quantum supremacy in driven quantum many-body systems” using complexity theory arguments is out as a preprint! We hope it will open the path for a large number of existing analog quantum simulators to showcase quantum supremacy and motivate further works in the field!
December 2019: Some of our group’s PhD and Final Year Diploma Theses are now available online. You can find them here.
November 2019: It was great to help organize two quantum programming workshops, one on IMB’s QSKIT and one on Google’s CIRQ where Dimitris delivered the opening and closing talks.
October 2019: Our group leader Dimitris was recently interviewed for OpenGov Asia on quantum computing and on Singapore’s Daily Today Online and on CNN Business about the recent quantum supremacy result by Google.
September 2019: Ben Tan, a new PhD student and a Singaporean joins the group. Welcome Ben!
August 2019: Tiang Feng defended her thesis with flying colours! Well done! All the best to your new adventures in the industry world!
