Influence of strong noise on coupled qubit systems — •Philipp Rudo, Michael Marthaler, and Gerd Schön — Institut für Theoretische Festkörperphysik, KIT, Karlsruhe

We investigate the influence of the environment on systems with coupled qubits. For this we assume that the coupling between the qubits as well as the coupling of the qubit to its environment is strong. In our model we are especially interested in the choice of basis when the qubit undergo an adiabatic evolution while the noise is static. To do so we introduced an rotation angle connecting the different bases of the adiabatic evolution and investigate its behavior over time.
