Enhancing quantum state transfer efficiency in binary-tree spin networks by partially collapsing measurements
Naghi Behzadi, Bahram Ahansaz
In this work, quantum state transfer (QST) over binary-tree spin networks is studied by using advantages of partially collapsing measurements. To this aim, we perform initially a w…
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…
A transition in the spectral statistics of quantum optical model by different electromagnetic fields
H. Sabri
The effects of the quantized electromagnetic fields on the spectral statistics of two-level atoms are considered. We have used the Berry- Robnik distribution and Maximum Likelihood…
Quantum coherence and entanglement preservation in Markovian and non-Markovian dynamics via additional qubits
Naghi Behzadi, Bahram Ahansaz, Esfandyar Faizi
In this paper, we investigate preservation of quantum coherence of a single-qubit interacting with a zero-temperature thermal reservoir through the addition of noninteracting qubit…
Effects of oscillatory deformations on the coherent and incoherent quantum transport
Naghi Behzadi, Bahram Ahansaz
Inspired by the works of [F. Caruso, New J. Phys. 16, 055015 (2014)] and [T. Scholak et al, J. Phys. B: At. Mol. Opt. Phys. 44 184012 (2011)], which state that for a large class of…
