Phase damping destroys quantum Fisher information of W states
(Elsevier Science BV, 2014-09-05)
We study the quantum Fisher information (QFI) of W states in the basic decoherence channels. We show that, as decoherence starts and increases, under i) depolarizing, QFI smoothly decays; ii) amplitude damping, QFI first ...
Fusing multiple W states simultaneously with a Fredkin gate
(American Physical Society, 2014-04-14)
We propose an optical scheme to prepare large-scale entangled networks of W states. The scheme works by simultaneously fusing three polarization-encoded W states of arbitrary size via accessing only one qubit of each W ...
Alpha head on collision with a fixed gold nucleus, taking into account the relativistic rest mass variation as implied by mass-energy equivalence
(Polish Acad Sciences Inst Physics, 2014-02)
We reformulate the Rutherford scattering of alpha particle for a head on collision, taking into account the rest mass variation of the particle, as implied by the energy conservation law. Our relativistic reformulation ...
Local elections and the Turkish voter: Looking for the determinants of party choice
(Routledge Journals, 2014-10-02)
On 30 March 2014 Turkish voters elected their local (city) councillors. Their party preferences seem to indicate considerable correspondence with the national vote choices. So, do voters' choices in local elections differ ...
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 ...
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 ...
On the analysis of expected distance between sensor nodes and the base station in randomly deployed WSNs
(Springer Verlag, 2014)
In this study, we focus on the analytical derivation of the expected distance between all sensor nodes and the base station (i.e., E[dtoBS]) in a randomly deployed WSN. Although similar derivations appear in the related ...
