Perfect state transfer over distance-regular spin networks
M. A. Jafarizadeh, R. Sufiani
By considering distance-regular graphs as spin networks, first we introduce some particular spin Hamiltonians which are extended version of those of Refs.\cite{8,9''}. Then, by usi…
Optimal Unambiguous Discrimination of Quantum States
M. A. Jafarizadeh, M. Rezaei, N. Karimi +1
Unambiguously distinguishing between nonorthogonal but linearly independent quantum states is a challenging problem in quantum information processing. In this work, an exact analyt…
Finite quantum tomography via semidefinite programming
M. A. Jafarizadeh, M. Mirzaee, M. Rezaee
Using the the convex semidefinite programming method and superoperator formalism we obtain the finite quantum tomography of some mixed quantum states such as: qudit tomography, N-q…
Investigation of continuous-time quantum walks via spectral analysis and Laplace transform
M. A. Jafarizadeh, R. Sufiani
Continuous-time quantum walk (CTQW) on a given graph is investigated by using the techniques of the spectral analysis and inverse Laplace transform of the Stieltjes function (Stiel…
Multi-qubit stabilizer and cluster entanglement witnesses
M. A. Jafarizadeh, G. Najarbashi, Y. Akbari +1
One of the problems concerning entanglement witnesses (EWs) is the construction of them by a given set of operators. Here several multi-qubit EWs called stabilizer EWs are construc…
Bell-states diagonal entanglement witnesses for relativistic and non-relativistic multispinor systems in arbitrary dimensions
M. A. Jafarizadeh, R. Sufiani
Two kinds of Bell-states diagonal (BSD) entanglement witnesses (EW) are constructed by using the algebra of Dirac matrices in the space-time of arbitrary dimension , where t…
