Quantum Steering of Two Tavis-Cummings Atoms with Dipole-Dipole Interaction Under Intrinsic Decoherence
Youssef Khouja, Abderrahim El Allati
Abstract Asymmetric and hybrid steering, evaluated by entropic uncertainty inequalities between two identical atoms, is studied in the Tavis-Cummings model with dipole-dipole interaction (DDI) under intrinsic decoherence. The results show that phase decoherence stabilizes the direction during time decay. DDI coupling in the system enhances bi-directionality and stability by avoiding collapses and violations, from which the asymmetric and hybrid steering suffer, respectively. When intrinsic decoherence is introduced, the asymmetric direction becomes stationary when DDI coupling is weak. However, the hybrid direction tends to have the same characteristics when DDI coupling is strong.
