We work on revealing novel many-body states and analyze quantum protected information in these states, and also study novel quantum fluids and disordered systems with non-conventional transport properties
Modern quantum technologies are oriented on creating prototypes of devices for quantum information processing in nanoscale. Success in these directions requires new ideas and theoretical support, and it was the purpose of creating the group “Many-body theory”. The group does quantum information processing and investigates non-standard superfluid/superconducting and disordered systems.
Scientists of the group investigate phase transitions of dipolar bosons in a 1D lattice with on-site disorder and analyze the achievement of quantum advantage. Besides that the group studies possible ways of transferring highly excited diatomic molecules in optical fibers to the ground state and the creation of qudits for quantum information processing.
The group also develops qudit schemes using diatomic molecules (of different atoms) in optical lattices for quantum calculations and studies the problem of quanrum advantage in many-body systems.
