Quantum speedup, non-Markovianity and formation of bound state
Bahram Ahansaz, Abbas Ektesabi
In this paper, we investigate the relationship between the quantum speedup, nonMarkovianity and formation of a system-environment bound state. Previous results show a monotonic rel…

Well-protected quantum state transfer in a dissipative spin chain
Naghi Behzadi, Abbas Ektesabi, Bahram Ahansaz
In this work, a mechanism for improving the quantum state transfer efficiency in a spin chain, which is in contact with a dissipative structured reservoir, is investigated. The eff…

Quantum speed limit time for a two-qubit system interacting with independent and common reservoirs
N. Behzadi, A. Ektesabi, B. Ahansaz +1
We study the quantum speed limit time for a two-qubit system interacts with indepen- dent and common reservoir. The system is initially prepared in a class of X-structure density m…
