Open quantum system description of singlet-triplet qubits in quantum dots
L. K. Castelano, F. F. Fanchini, K. Berrada
We develop a theoretical model to describe the dissipative dynamics of singlet-triplet qubits in GaAs quantum dots. Using the concurrence experimentally obtained [M. D. Shulman et…
Open quantum system description of singlet-triplet qubits in quantum dots
L. K. Castelano, F. F. Fanchini, K. Berrada
We develop a theoretical model to describe the dissipative dynamics of singlet-triplet (S-T_0) qubits in GaAs quantum dots. Using the concurrence experimentally obtained as a guide…
Nonlocal correlations for manifold quantum systems: Entanglement of two-spin states
K. Berrada, A. Mohammadzade, S. Abdel-Khalek +2
In this paper, we study the bipartite entanglement of spin coherent states in the case of pure and mixed states. By a proper choice of the subsystem spins, the entanglement for lar…
Quantum correlations between each qubit in a two-atom system and the environment in terms of interatomic distance
K. Berrada, F. F. Fanchini, S. Abdel-Khalek
The quantum correlations between a qubit and its environment are described quantitatively in terms of interatomic distance. Specifically, considering a realistic system of two two-…
Concurrence for a two-qubits mixed state consisting of three pure states in the framework of SU(2) coherent states
S. Salimi, A. Mohammadzade, K. Berrada
A simplified expression of concurrence for two-qubit mixed state having no more than three non-vanishing eigenvalues is obtained. Basing on SU(2) coherent states, the amount of ent…
Generalized Heisenberg algebra coherent states for Power-law potentials
Kamal Berrada, Morad El Baz, Yassine Hassouni
Coherent states for power-law potentials are constructed using generalized Heisenberg algabras. Klauder's minimal set of conditions required to obtain coherent states are satisfied…
