Quantum fisher information of a 3 x 3 bound entangled state and its relation with geometric discord
(Springer/Plenum Publishers, 2015-09)
Recent studies on quantum Fisher information (QFI) have been focused mostly on qubit systems within the context of how entanglement helps surpassing the classical limit of separable states and the limit that a given entangled ...
Analysis of entanglement measures and LOCC maximized quantum fisher information of general two qubit systems
(Nature Publishing Group, 2014-06-24)
Entanglement has been studied extensively for unveiling the mysteries of non-classical correlations between quantum systems. In the bipartite case, there are well known measures for quantifying entanglement such as ...
Constructing quantum logic gates using q-deformed harmonic oscillator algebras
(Springer, 2014-04)
We study two-level q-deformed angular momentum states, and using q-deformed harmonic oscillators, we provide a framework for constructing qubits and quantum gates. We also present the construction of some basic one-qubit ...
Quantum fisher information of several qubitsin the superposition of A GHZ and two W stateswith arbitrary relative phase
(Springer/Plenum Publishers, 2014-09)
We study the quantum Fisher information (QFI) of a system of several particles which is in a superposition of a GHZ and two W states with arbitrary relative phase. We show that as the number of particles increases from 3 ...
NFC internal: An indoor navigation system
(MDPI AG, 2015-04)
Indoor navigation systems have recently become a popular research field due to the lack of GPS signals indoors. Several indoors navigation systems have already been proposed in order to eliminate deficiencies; however each ...
Behavior of quantum fisher information of bell pairs under decoherence channels
(Polish Acad Sciences Inst Physics, 2014-02)
Quantum Fisher information has recently been an essential tool for analyzing the phase sensitivity of the quantum states in various quantum tasks, requiring high precision, such as quantum clock synchronization, positioning ...
Optimal deployment in randomly deployed heterogeneous WSNs: A connected coverage approach
(Academic Press Ltd- Elsevier Science Ltd, 2014-11)
Wireless sensor networks (WSNs) are resource-scarce networks and the optimization of the resources is challenging. As far as random deployment is concerned, the optimization of these resources becomes even more difficult ...
NFC Loyal for enhancing loyalty services through Near Field Communication
(Springer US, 2013-02)
Near Field Communication (NFC) as an emerging technology is currently leveraged by large standardization efforts and tries to find a suitable ecosystem. NFC enabled mobile devices with integrated smart cards introduce ...
The sectoral sweeper scheme for wireless sensor networks: Adaptive antenna array based sensor node management and location estimation
(Kluwer Academic Publishers-Plenum Publishers, 2006-12)
We introduce a novel sensor node management and location estimation method referred as sectoral sweeper (SS) scheme that uses an adaptive antenna array (AAA) at a central node in wireless sensor networks (WSNs). With the ...
Quarantine region scheme to mitigate spam attacks in wireless sensor networks
(IEEE, 2006-08)
The Quarantine Region Scheme (QRS) is introduced to defend against spam attacks in wireless sensor networks where malicious antinodes frequently generate dummy spam messages to be relayed toward the sink. The aim of the ...
