Parameter estimation with Dzyaloshinskii–Moriya interaction under external magnetic fields
(Springer, 2020-02-01)
We study the effects of external magnetic fields on the precision of parameter estimation with thermal entanglement of two spins in XX model, in the presence of Dzyaloshinskii–Moriya (DM) interaction. Although DM interaction ...
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 ...
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 ...
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 ...
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 ...
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 ...
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. ...
İki qubit’lik kuantum haberleşme ağlarının eş zamanlılık donanıklık ölçütü ile kuantum Fisher bilgisinin analizi
(IEEE, 2014-06-12)
Kuantum dolanıklık, kuantum haberleşme mühendisliğinin en temel kavramlarından biridir. Kuantum sistemlerin dolanıklık ölçütlerine göre sıralanması günümüzde oldukça çok çalışılan
konulardan birisidir. İki parçacıklı iki ...
Temperature control in dissipative cavities by entangled dimers
(Amer Chemical Soc, 2019-02-21)
We show that the temperature of a cavity field can be drastically varied by its interaction with suitably entangled atom pairs (dimers) traversing the cavity under realistic atomic decoherence. To this end we resort to the ...
Work and heat value of bound entanglement
(Springer, 2019-12)
Entanglement has recently been recognized as an energy resource which can outperform classical resources if decoherence is relatively low. Multi-atom entangled states can mutate irreversibly to so-called bound entangled ...
