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.

December 2020: We have been busy this month. Three of our works are out, two preprints and one publication ! (1) New work out on machine learning with topology (persistent homology) for probing exotic topological bands in condensed matter physics. (2) Our preprint on one on analog quantum machine learning with near term quantum processors is published in Physical Review Research. (3) Our new work on quantum supremacy and quantum phase transition is out as preprint! We propose how our quantum supremacy proposal with driven analog many-body systems can also be used for probing phases of matter.
November 2020: Dimitris was interviewed on Deutsch Welle News Asia on the recent quantum supremacy experiment in China. Check out the interview here.
September 2020: Two new PhD students and a Senior Research Fellow join us. Chee, Beng Yee and Daniel. Welcome guys!
July 2020: New work on qubit efficient algorithms for solving binary optimization problems is out as preprint! We propose and analyze a set of variational quantum algorithms for solving quadratic unconstrained binary optimization problems where a problem consisting of n classical variables can be implemented on O(log(n))number of qubits.
May 2020: Our new work on analog quantum processors for machine learning is out as a preprint! We discuss how the interplay between external driving and disorder in quantum many-body systems can dictate their trainability and expressibility and apply it to solve a generative modelling problem.
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!
