A novel approach to the systematization of alpha-decaying nuclei, based on shell structures
(Springer, 2016-05-24)We provide a novel systematization of alpha-decaying nuclei, starting with the classically adopted mechanism. The decay half-life of an alpha-disintegrating nucleus is framed, supposing that i) the alpha-particle is born ... -
Deterministic generation of large scale atomic W states
(Optical Soc Amer, 2016-05-30)We present a deterministic scheme for generating large-scale atomic W states in a cavity QED system via a simple expansion mechanism, which is realized only by a detuned interaction between two identical atoms and a vacuum ... -
SIMSec: A key exchange protocol between SIM card and service provider
(Springer New York LLC, 2016-08-01)Mobile technology is so popular and overdosed adoption is inevitable in today’s world. As the mobile technologies have advanced, Service Providers (SP) have offered services via Smartphones and some of them required secure ... -
Generating multi-photon W-like states for perfect quantum teleportation and superdense coding
(Springer New York LLC, 2016-05-06)An interesting aspect of multipartite entanglement is that for perfect teleportation and superdense coding, not the maximally entangled W states but a special class of non-maximally entangled W-like states are required. ... -
Incremental reasoning on monadic second-order logics with logic programming
(Elsevier Science Inc, 2016-02)Data streams occur widely in various real world applications. The research on streaming data mainly focuses on the data management, query evaluation and optimization on data, but the work on incremental reasoning procedures ... -
Generating multi-atom entangled W states via light-matter interface based fusion mechanism
(Nature Publishing Group, 2015-11-09)W state is a key resource in quantum communication. Fusion technology has been proven to be a good candidate for preparing a large-size W state from two or more small-size W states in linear optical system. It is of great ... -
Quantum metrology: Surpassing the shot-noise limit with Dzyaloshinskii-Moriya interaction
(Nature Publishing Group, 2015-11-09)Entanglement is at the heart of quantum technologies such as quantum information and quantum metrology. Providing larger quantum Fisher information (QFI), entangled systems can be better resources than separable systems ... -
Governance of technology and innovation policy mix: The estonian experience since 2000
(Canadian Center of Science and Education, 2015)Technology and innovation policies began to be implemented in Estonia in the 2000s, a time when the country’s governance system for technology and innovation policy was still weak. However, by building strong institutions, ... -
Enhancing the W state fusion process with a toffoli gate and a CNOT gate via one-way quantum computation and linear optics
(Polish Acad Sciences Inst Physics, 2015-04)Creation of large-scale W state quantum networks is a key step for realization of various quantum information tasks. Regarding the photonics technology, a simple optical setup was proposed for the fusion of two W states. ... -
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 ... -
Optimal deployment in randomly deployed heterogeneous WSNs: A connected coverage approach (vol 46, pg 182, 2014)

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 ... -
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 ... -
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 ... -
Alpha head on collision with a fixed gold nucleus, taking into account the relativistic rest mass variation as implied by mass-energy equivalence

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 ... -
