Absorption free superluminal light propagation in a three level pump-probe system
M. Mahmoudi, S. Worya Rabiei, L. Ebrahimi Zohravi +1
We investigate the dispersion and the absorption properties of a weak probe field in a three-level pump-probe atomic system. It is shown that the slope of dispersion changes from p…
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…
Group velocity control in the ultraviolet domain via interacting dark-state resonances
M. Mahmoudi, M. Sahrai, J. Evers
The propagation of a weak probe field in a laser-driven four-level atomic system is investigated. We choose mercury as our model system, where the probe transition is in the ultrav…
Geometry of Two-Qubit State and Intertwining Quaternionic Conformal Mapping Under Local Unitary Transformations
G. Najarbashi, S. Ahadpour, M. A. Fasihi +1
In this paper the geometry of two-qubit systems under local unitary group is discussed. It is shown that the quaternionic conformal map intertwines between thi…
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…
