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…
Virtual excitations and entanglement dynamics and polygamy in three ultra-strongly coupled systems
Radouan Hab-arrih, Ahmed Jellal
The Milburn dynamics of three nonresonant ultra-strongly coupled oscillators are resolved by using symplectic geometry. We look at the Milburn dynamics of virtual excitations and h…
Virtual excitations and quantum correlations in ultra-strongly coupled harmonic oscillators under intrinsic decoherence
Radouan Hab-arrih, Ahmed Jellal, El Hassan El Kinani
We study the intrinsic decoherence of coupled harmonic oscillators. The Milburn master equation is solved exactly, and the dynamics of virtual ground state excitations are investig…
Implementing quantum Fourier transform using three qubits
Mouhcine Yachi, Radouan Hab-arrih, Ahmed Jellal
Using the circulant symmetry of a Hamiltonian describing three qubits, we realize the quantum Fourier transform. This symmetry allows us to construct a set of eigenvectors independ…
Dynamics of Non-Gaussian Entanglement of Two Magnetically Coupled Modes
Radouan Hab-arrih, Ahmed Jellal, Abdeldjalil Merdaci
This paper surveys the quantum entanglement of two coupled harmonic oscillators via angular momentum generating a magnetic coupling . The corresponding Hamiltonian is diagon…
Classical Instability Effects on Photon Excitations and Entanglement
Radouan Hab-arrih, Ahmed Jellal, Abdeldjalil Merdaci
The Schrödinger dynamics of photon excitation numbers together with entanglement in two non-resonant time-dependent coupled oscillators is investigated. By considering periodi…
