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…
Enhancement of quantum transport efficiency in a noisy spin channel
Naghi Behzadi, Bahram Ahansaz, Abbas Ektesabi
In this paper, based on the notion of pseudomode framework introduced by Garraway in [Phys. Rev. A 55, 2290 (1997)], we propose a mechanism for enhancing the efficiency of excitati…
Controlling speedup in open quantum systems through the manipulating of system-reservoir bound states
N. Behzadi, B. Ahansaz, A. Ektesabi +1
In this paper, we give a mechanism for controlling speedup of a single-qubit open quantum system by exclusively manipulating the system-reservoir bound states using additional non-…
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…
An improved bound for quantum speed limit time in open quantum systems by introducing an alternative fidelity
Abbas Ektesabi, Naghi Behzadi, Esfandyar Faizi
In this paper, we introduce a new alternative quantum fidelity for quantum states which perfectly satisfies all Jozsas axioms and is zero for orthogonal states. By employing this f…
Effect of two-qutrit entanglement on quantum speed limit time of a bipartite V-type open system
N. Behzadi, B. Ahansaz, A. Ektesabi +1
In the present paper, quantum speed limit (QSL) time of a bipartite V-type three-level atomic system under the effect of two-qutrit entanglement is investigated. Each party interac…
