Characterization of qutrit channels in terms of their covariance and symmetry properties
Vahid Karimipour, Azam Mani, Laleh Memarzadeh
We characterize the completely positive trace-preserving maps on qutrits (qutrit channels) according to their covariance and symmetry properties. Both discrete and continuous group…
Stationary entanglement achievable by environment induced chain links
Laleh Memarzadeh, Stefano Mancini
We investigate the possibility of chaining qubits by letting pairs of nearest neighbours qubits dissipating into common environments. We then study entanglement dynamics within the…
Forgetfulness of continuous Markovian quantum channels
Cosmo Lupo, Laleh Memarzadeh, Stefano Mancini
The notion of forgetfulness, used in discrete quantum memory channels, is slightly weakened in order to be applied to the case of continuous channels. This is done in the context o…
New Phase Transitions in Optimal States for Memory Channels
Vahid Karimipour, Zohreh Meghdadi, Laleh Memarzadeh
We investigate the question of optimal input ensembles for memory channels and construct a rather large class of Pauli channels with correlated noise which can be studied analytica…
The matrix product representations for all valence bond states
Vahid Karimipour, Laleh Memarzadeh
We introduce a simple representation for irreducible spherical tensor operators of the rotation group of arbitrary integer or half integer rank and use these tensor operators to co…
Entanglement and quantum phase transitions in matrix product spin one chains
S. Alipour, V. Karimipour, L. Memarzadeh
We consider a one-parameter family of matrix product states of spin one particles on a periodic chain and study in detail the entanglement properties of such a state. In particular…
