Quantum Information Technologies

The group is investigating the potential of quantum systems in terms of its use in information technology. We study quantum-optical systems, as well as multiparticle ensembles of ultracold gases of atoms, molecules, and excitons. Our group has developed new protocols and post-processing algorithms for quantum communication systems, as well as new approaches to quantum information processing. We are also studying the potential of classical machine learning to describe quantum phenomena and the possible acceleration of machine learning algorithms through the use of quantum computing. We work closely with colleagues from the University of Paris-Sud, University of Oxford, Centre for Quantum Technologies in Singapore (CQT), Steklov Mathematical Institute of Russian Academy of Sciences, and Skoltech.

We have developed a protocol for a quantum-protected blockchain [Nature (London) 563, 465 (2018); Quantum Sci. Technol. 3, 035004 (2018)], and our error correction algorithm in quantum communication systems demonstrates record-breaking indicators in terms of efficiency [Phys. Rev. Appl. 8, 044017 (2017)].
