Entanglement generation between a charge qubit and its bosonic environment during pure dephasing: Dependence on the environment size

Author(s): Tymoteusz Salamon and Katarzyna Roszak
We study entanglement generated between a charge qubit and a bosonic bath due to their joint evolution which leads to pure dephasing of the qubit. We tune the parameters of the interaction, so that the decoherence is quantitatively independent of the number of bosonic modes taken into account and in...
