We will investigate possible applications of controlled transfer of topological excitations in a lattice with ring-like cells for measuring rotation and acceleration in a wide dynamic range and for processing quantum information in an experimentally achievable qubit system. popup.description2 Research object: quantum vortices, superfluid currents in Bose-Einstein condensates of atomic gases. Purpose of the work: to develop new methods for control of the transport of stable topological excitations in atomic quantum gases for application in ultra-sensitive quantum sensors and quantum information systems, to investigate possi-bilities for non-destructive manipulation of quantum vortices in ultra-cold quantum gases. Research methods: dissipative mean-field theory, stochastic Gross-Pitaevskii equation, numerical methods. Results and novelty. The theoretical possibility to utilize the transport of superfluid flows as an instrument for acceleration and rotation sensing was shown for the first time in the literature. Systems formed from ring atomic Bose-Einstein condensates in various spatial configurations have been studied and the sensitivity of various physical effects to external acceleration was shown, including vortex transport and the Josephson effect. The dynamics of vortex lines in exciton-polariton and self-gravitating condensates was studied in detail. A new method for non-destructive measurement of a quantum state in toroidal Bose condensates was proposed.   Product Description popup.authors Bazhan Nataliia V. Borysenko Yurii V.
