Dynamics of quantum entanglement in two time-dependent coupled harmonic oscillators
Ayoub Ghaba, Radouan Hab-arrih, Elhoussine Atmani +1
We investigate the quantum entanglement dynamics of two coupled harmonic oscillators with a time-dependent interaction. Using the Lewis-Riesenfeld invariant method, we derive the e…
Einstein-Podolsky-Rosen Steering in Three Coupled Harmonic Oscillators
Ayoub Ghaba, Radouan Hab Arrih, Elhoussine Atmani +1
Quantum steering is one of the most intriguing phenomena in quantum mechanics and is essential for understanding correlations in multi-body systems. Despite its importance, analyti…
Assessing the entanglement of three coupled harmonic oscillators
Ayoub Ghaba, Radouan Hab Arrih, Elhoussine Atmani +2
Quantum entanglement serves as a key phenomenon in understanding correlations in many-body systems, but analytical results remain scarce for coupled three-body oscillators. In this…
Quantum steering and entanglement for coupled systems: exact results
Radouan Hab arrih, Ayoub Ghaba, Ahmed Jellal
Using the Wigner function in phase space, we study quantum steering and entanglement between two coupled harmonic oscillators. We derive expressions for purity and quantum steering…
