Super quantum discord for a class of two-qubit states with weak measurement
H. Eftekhari, E. Faizi
So far, super quantum discord has been calculated explicitly only for Bell-diagonal states and expressions for more general quantum states are not known. In this paper, we derive e…
Local quantum uncertainty of SU(2) invariant states
E. Faizi, B. Ahansaz Salmasi
In this paper, we investigated quantum correlation in SU (2) invariant quantum spin systems by local quantum uncertainty(LQU). These states are invariant under global rotations of…
Investigation of the Quantum Correlations for a S=1/2 Ising- Heisenberg Model on a Symmetrical Diamond Chain
E. Faizi, H. Eftekhari
We consider the quantum correlations for a S=1/2 Ising- Heisenberg model of a symmetrical diamond chain. Firstly, we compare concurrence, quantum discord and 1- norm geometric quan…
Comparison of quantum discord and local quantum uncertainty in a vertical quantum dot
E. Faizi, H. Eftekhari
In this paper, we consider quantum correlations (quantum discord and local quantum uncertainty) in a vertical quantum dot. Their dependencies on magnetic field and temperature are…
Quantum discord and one-norm geometric quantum discord for XXX Heisenberg spin chain under noisy channels
E. Faizi, H. Eftekhari
Here, we compare the behavior of the quantum discord, 1-norm geometric quantum discord and concurrence under the effect of decoherence for XXX Heisenberg spin chain. Their dependen…
