Entanglement generation in the ultra-strongly coupled Rabi model / M. Bina, S. Maffezzoli Felis, S. Olivares. - In: INTERNATIONAL JOURNAL OF QUANTUM INFORMATION. - ISSN 0219-7499. - 12:7/8(2014 Dec 18), pp. 1560016.1-1560016.11. [10.1142/S0219749915600163]
Abstract:
We analyze the dynamics of the quantum Rabi model for two qubits interacting through a common bosonic field (resonator), focusing on the generation and detection of maximally entangled states. We obtain analytical results for the unitary dynamics of this system in the slow-qubit (or degenerate) regime, considering ultra-strong coupling between qubits and resonator mode, for which the rotating wave approximation (RWA) is no longer applicable. We also numerically investigate the dynamics beyond the slow-qubit condition in order to study the validity of the model in the presence of less strict conditions.
