Decoherence due to an excited state quantum phase transition in a two-level boson model
P. Perez-Fernandez, A. Relano, J. M. Arias +2
The decoherence induced on a single qubit by its interaction with the environment is studied. The environment is modelled as a scalar two-level boson system that can go through eit…
