Distance growth of quantum states due to initial system--environment correlations
J. Dajka, J. Luczka
Intriguing features of the distance between two arbitrary states of an open quantum system are identified that are induced by initial system-environment correlations. As an example…

Geometric phase as a determinant of a qubit--environment coupling
J. Dajka, J. Luczka, P. Hanggi
We investigate the qubit geometric phase and its properties in dependence on the mechanism for decoherence of a qubit weakly coupled to its environment. We consider two sources of…
