Alpha head on collision with a fixed gold nucleus, taking into account the relativistic rest mass variation as implied by mass-energy equivalence
Yarman, Nuh Tolga; Arık, Metin; Kholmetskii, Alexander; Altıntaş, Azmi Ali; Özaydın, Fatih (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 ... -
Analysis of entanglement measures and LOCC maximized quantum fisher information of general two qubit systems
Erol, Volkan; Özaydın, Fatih; Altıntaş, Azmi Ali (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 ... -
Behavior of quantum fisher information of bell pairs under decoherence channels
Özaydın, Fatih; Altıntaş, Azmi Ali; Buğu, Sinan; Yeşilyurt, Can (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 ... -
Constructing quantum logic gates using q-deformed harmonic oscillator algebras
Altıntaş, Azmi Ali; Özaydın, Fatih; Yeşilyurt, Can; Buğu, Sinan; Arık, Metin (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 ... -
Deterministic local doubling of W states
Özaydın, Fatih; Yeşilyurt, Can; Buğu, Sinan; Altıntaş, Azmi Ali; Tame, Mark S.; Yang, Lan; Özdemir, Şahin Kaya (OSA - The Optical Society, 2016-11-01)In large quantum systems, multipartite entanglement can be found in many inequivalent classes. Preparing states of arbitrary size in different classes is important for performing a wide range of quantum protocols. W states, ... -
Fusing multiple W states simultaneously with a Fredkin gate
Özaydın, Fatih; Buğu, Sinan; Yeşilyurt, Can; Altıntaş, Azmi Ali; Tame, Mark; Kaya Özdemir, Şahin (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 ... -
A novel approach to the systematization of alpha-decaying nuclei, based on shell structures
Yarman, Nuh Tolga; Zaim, Nimet; Kholmetskii, Alexander; Arık, Metin; Altıntaş, Azmi Ali; Özaydın, Fatih; Susam, Lidya Amon (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 ... -
Parameter estimation with Dzyaloshinskii–Moriya interaction under external magnetic fields
Özaydın, Fatih; Altıntaş, Azmi Ali (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 ... -
Quantum fisher information of bipartitions of W states
Özaydın, Fatih; Altıntaş, Azmi Ali; Yeşilyurt, Can; Buğu, Sinan; Erol, Volkan (Polish Acad Sciences Inst Physics, 2015-04-24)We study the quantum Fisher information (QFI) of W states and W-like states under decoherence. In particular, we find that on the contrary to amplitude damping and depolarizing decoherence, a W-like state of 3 qubits ... -
Quantum fisher information of several qubitsin the superposition of A GHZ and two W stateswith arbitrary relative phase
Özaydın, Fatih; Altıntaş, Azmi Ali; Buğu, Sinan; Yeşilyurt, Can; Arık, Metin (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 ... -
Quantum metrology: Surpassing the shot-noise limit with Dzyaloshinskii-Moriya interaction
Özaydın, Fatih; Altıntaş, Azmi Ali (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 ...
