Kok Wee Song, Postdoctoral Research Fellow

Kok Wee Song

Kok Wee obtained his Bachelor's degree at National Tsing-Hua University (Taiwan) and completed his Ph.D. at the University of Southern California (US) in physics.

After graduation, he was a postdoc at Argonne National Laboratory (US), focusing on the theory of multiband superconductivity. Then, he moved to National Graphene Institute (UK), working on the optical properties and electronic correlation effects on 2D materials as a research associate.

From 2021, he is the postdoctoral research fellow at the University of Exeter, QuDOS group.

His primary research background is in the emergent phenomena of quantum many-body systems. Until recently, he has developed a lot of interest in quantum optics with 2D materials, and currently leads the research in nonlinear polaritonics based on transition metal dichalcogenide monolayers.


Annie Paine, PhD student

Annie Paine

Annie received her Bachelor degree in Mathematics at University of Oxford (UK) in 2018. She finished Master degree in Mathematical and Theoretical Physics at University of Oxford (UK) in 2019.

Between years at university she has completed two internships, both of which were programming related. There she improved her programming skills (particularly in C++, Python and Rust) as well as experiencing working in a team in a professional setting. At her second internship with Metaswitch Annie gained experience in presenting her works progress and results as she was placed in a team which had daily meetings in which everyone reported their progress.

From 2020 Annie is a PhD student at the University of Exeter, sponsored by Qu & Co and supervised by Dr Kyriienko.

Her project is focused on finding useful quantum algorithms with near-term quantum devices. To deal with the limitations of near-term quantum devices she is particularly interested in hybrid and variational approaches. The areas of application that she is focused on include differential equations, which permeate many different areas of study, and finding the ground state energy of a system, a question of great interest in computational chemistry.


Salvatore Chiavazzo, PhD student

Salvatore Chiavazzo

Salvatore finished his Bachelor degree in Physics at the University of Naples (Italy) in 2017. He acomplished his Master degree in Physics (Condensed Matter training track) at the University of Trieste (Italy) in 2019.

During 2019 he was a visitor at the Institute for Quantum Computing, Waterloo (Canada), to carry out a master thesis project. The research stay was funded with the Extra-Erasmus scholarship.

From 2020 Salvatore is PhD student at the University of Exeter, QuDOS group.

Salvatore's research is focused on two-dimensional materials, strong light-matter coupling, and optomechanics. To date, he has successfully described and characterized of two-phonon cooling in electromechanical systems that operate in microwave domain, and introduced the effects of strong coupling to doped TMD systems.

His current research activity includes theoretical description of dipolaritons in TMD bilayers and its application to single photon emission.


Chukwudubem Umeano, PhD student

Chiddy Umeano

Chukwudubem completed his Bachelor’s degree in Physics at the University of Warwick (UK) in 2020. He finished his Master’s degree in Quantum Fields and Fundamental Forces at Imperial College London (UK) in 2021.

His final project at undergraduate level was based on applying Python and machine learning techniques to classify crystal structures. For his master thesis, he wrote a survey of quantum algorithms. Through several projects and courses, he has become comfortable with programming in Python and C.

From 2021 Chukwudubem is a PhD student at the University of Exeter, QuDOS group.

His project is focused on developing a theory for quantum feature maps. He is investigating different methods for encoding classical data into quantum states, with the aim of constructing highly expressive quantum circuits for use within quantum machine learning.

Tatiana Bespalova

Tatiana Bespalova

In 2020 Tatiana applied for an internship at University of Exeter as a part of research collaboration with QuDOS group. While working under mentorship of Dr Oleksandr Kyriienko she developed the protocol for Hamiltonian operator approximation, being a tool for energy estimation needed in various algorithms. Currently, she researches new variational ansatze and simulation schemes for complex spin models.

Her research during the education included performing molecular modeling and also an exploration of nonperturbative effects in quantum field theory. She hopes to develop or realize quantum algorithms to solve some of the problems in these areas one day. After her bachelor graduation she has decided to take the challenge of exploring the quantum computing. As there is no courses on this topic in Russia she has studied it by herself with the book of Nielsen and Chuang and other literature. Having got the basic knowledge in the field of quantum computations she started research on Hamiltonian operator simulation.

Tatiana will continue her scientifical path as a PhD student, joining group at IBM Zürich, Switzerland.
