Quantum correlations and coherence in a two-qubit anisotropic under magnetic field
Ahmed Jellal, Pablo DÃaz, David Laroze
We study thermal quantum correlations and coherence in Heisenberg model with anisotropic interactions under a uniform magnetic field . Using concurrence , local quantu…
Quasi-Orthogonal Stabilizer Design for Efficient Quantum Error Suppression
Valentine Nyirahafashimana, Sharifah Kartini Said Husain, Umair Abdul Halim +2
Orthogonal geometric constructions are the basis of many many quantum error-correcting codes (QEC), but strict orthogonality constraints limit design flexibility and resource effic…
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…
Entanglement distribution in pure non-Gaussian tripartite states: a Schmidt decomposition approach
Abdeldjalil Merdaci, Ahmed Jellal
We study entanglement in a system of three coupled quantum harmonic oscillators. Specifically, we use the Schmidt decomposition to analyze how the entanglement is distributed among…
Transforming qubits via quasi-geometric approaches
Nyirahafashimana Valentine, Nurisya Mohd Shah, Umair Abdul Halim +2
We develop a theory based on quasi-geometric (QG) approach to transform a small number of qubits into a larger number of error-correcting qubits by considering four different cases…
