Analytic Benchmarks for Coherence-to-Entanglement Conversion under Post-Gate Noise in CNOT-Based Protocols
Asad Ali, H. Kuniyil, M. I. Hussain +3
Coherence-to-entanglement conversion transforms single-qubit superposition into a practical two-qubit resource, but noise limits this process in near-term quantum hardware. We deri…
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…
Influence of quantum decoherence on the survival of quantumness in neutrino oscillations
Jilali Loulijat, Abdallah Slaoui, Mohamed Gouighri +1
This study examines the dynamics of quantumness in two-flavor neutrino oscillations subjected to a dephasing channel, using representative oscillation parameters associated with th…
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…
