Reference state for arbitrary U-consistent subspace
Iman Sargolzahi
The reduced dynamics of the system , interacting with the environment , is not given by a linear map, in general. However, if it is given by a linear map, then this map is al…
Entanglement increase from local interaction in the absence of initial quantum correlation in the environment and between the system and the environment
Iman Sargolzahi, Sayyed Yahya Mirafzali
We consider a bipartite quantum system S=AB such that the part A is isolated from the environment E and only the part B interacts with E. Under such circumstances, entanglement of…
Optimization by a quantum reinforcement algorithm
A. Ramezanpour
A reinforcement algorithm solves a classical optimization problem by introducing a feedback to the system which slowly changes the energy landscape and converges the algorithm to a…
Entanglement revival can occur only when the system-environment state is not a Markov state
Iman Sargolzahi
Markov states have been defined for tripartite quantum systems. In this paper, we generalize the definition of the Markov states to arbitrary multipartite case and find the general…
When the assignment map is completely positive
Iman Sargolzahi, Sayyed Yahya Mirafzali
Finding the general set of system-environment states for which the reduced dynamics of the system is completely positive (CP) is the subject of some recent works. An advance in thi…
