QUTE SLOVAKIA
In connection with the preparation of European Commission project "Quantum Flagship" the Presidum of Slovak Academy of Sciences is organizing an informal seminar aiming to introduce this project for Slovak researchers, to formulate our national priorities within the area of quantum technologies and to outline Slovak-wide supporting innitiative in the area of quantum technologies.

Signatures of Hyperfine, Spin-Orbit, and Decoherence Effects in a Pauli Spin Blockade
We detect in real time interdot tunneling events in a weakly coupled two-electron double quantum dot in GaAs. At finite magnetic fields, we observe two characteristic tunneling times Td and Tb, belonging to, respectively, a direct and a blocked (spin-flip-assisted) tunneling. The latter corresponds to the lifting of a Pauli spin blockade, and the tunneling times ratio η=Tb/Td characterizes the blockade efficiency. We find pronounced changes in the behavior of η upon increasing the magnetic field, with η increasing, saturating, and increasing again. We explain this behavior as due to the crossover of the dominant blockade-lifting mechanism from the hyperfine to spin-orbit interactions and due to a change in the contribution of the charge decoherence.
