Oleksandr KyriienkoDr. Oleksandr Kyriienko is a Ukrainian theoretical physicist working in the fields of quantum optics, condensed matter physics, and quantum computing. 

Currently he is a Lecturer (Assistant Professor) at the Physics department of the University of Exeter. Previously he was a Fellow at the Nordic Institute for Theoretical Physics (NORDITA), located in Stockholm, Sweden. He did postdoctoral research at the Niels Bohr Institute, University of Copenhagen, and obtained the PhD degree from the University of Iceland.

Dr Kyriienko started out as a theoretical physicist in condensed-matter physics, but he applied it to optics and semiconductor systems that are used to create lasers, which are actively used in the industry. In particular, he has been working on a theoretical design of a new type of lasers called “polariton lasers”. Since quantum optical systems have other excellent properties, like the ability to process quantum information and distribute it in the network, he grew strong interested in quantum computing and has a strong focus on the area. Herem, the combination of strong light-matter coupling and quantum information processing represents the ultimate goal, leading to development of quantum polaritonics.

Group Members

 ♦ Salvatore Chiavazzo PhD student

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

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

From 2020 – PhD student at the University of Exeter in the QuDOS group.

Salvatore Chiavazzo 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. 

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

 ♦ Annie Paine PhD student

Annie recived her Bachelor in Mathematics at University of Oxford (UK) 2018. And finished Master degree in Mathematical and Theoretical Physics at University of Oxford (UK) 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 in Quantum Computing group under the supervision of Dr. Kyriienko at the University of Exeter.

Her project is focused on finding useful quantum algorithms for 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. 

 ♦ Tatiana Bespalova MSc student as a part of research collaboration 

Tatiana has accomplished her Bachelor degree in Applied Mathematics and Physics at Saint Petersburg Academic University (Saint Petersburg, Russia), 2019

From 2019 Tatiana is a MSc student at ITMO University (Saint Petersburg, Russia)

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 area of quantum computations. 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. In 2020 Tatiana applied for an internship at University of Exeter as a part of research collaboration with QuDOS group and to work personally with Dr. Oleksandr Kyriienko as her superviser to perform a research on Hamiltonian operator simulation.
