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…
Entanglement and optimal strings of qubits for memory channels
V. Karimipour, L. Memarzadeh
We investigate the problem of enhancement of mutual information by encoding classical data into entangled input states of arbitrary length and show that while there is a threshold…
Transition behavior in the capacity of correlated-noisy channels in arbitrary dimensions
V. Karimipour, L. Memarzadeh
We construct a class of quantum channels in arbitrary dimensions for which entanglement improves the performance of the channel. The channels have correlated noise and when the lev…
