Generalized lorentz group of space-time transformations
(Işık University Press, 2020)
We examine how Lorentz Symmetry (LS) breaks down in Yarman-Arik-Kholmetskii (YARK) theory of gravitation through an entirely different mechanism than that under metric theories of gravity. Said mechanism can be right away ...
Self-localized soliton solutions of the nonlinear quantum harmonic oscillator
(Işık University Press, 2022)
We analyze the existences, properties and stabilities of the self-localized solutions of the nonlinear quantum harmonic oscillator (NQHO) using spectral renormalization method (SRM). We show that self-localized single and ...
Preparing multipartite entangled spin qubits via pauli spin blockade
(Nature Research, 2020-02-26)
Preparing large-scale multi-partite entangled states of quantum bits in each physical form such as photons, atoms or electrons for each specific application area is a fundamental issue in quantum science and technologies. ...
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 ...
Surpassing the classical limit in magic square game with distant quantum dots coupled to optical cavities
(Nature Research, 2020-12-17)
The emergence of quantum technologies is heating up the debate on quantum supremacy, usually focusing on the feasibility of looking good on paper algorithms in realistic settings, due to the vulnerability of quantum systems ...
Powering quantum Otto engines only with q -deformation of the working substance
(American Physical Society, 2023-11)
We consider a quantum Otto cycle with a q-deformed quantum oscillator working substance and classical thermal baths. We investigate the influence of the quantum statistical deformation parameter q on the work and efficiency ...
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 ...
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 ...
Engineering four-qubit fuel states for protecting quantum thermalization machine from decoherence
(Multidisciplinary Digital Publishing Institute (MDPI), 2024-01-10)
Decoherence is a major issue in quantum information processing, degrading the performance of tasks or even precluding them. Quantum error-correcting codes, creating decoherence-free subspaces, and the quantum Zeno effect ...
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. ...
