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 ...
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 ...
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 ...
An optical setup for deterministic creation of four Partite W state
(Polish Academy of Sciences, 2015-04)
In order to create polarization based entanglement networks of W-4 state, we propose an optical setup, which uses only four horizontally polarized photons as resource which implies no entanglement requirement as a resource. ...
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 ...
Quantum fisher information of bipartitions of W states
(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 ...
Superactivating bound entanglement in quantum networks via quantum Zeno dynamics and a novel algorithm for optimized Zeno evolution
(MDPI, 2023-01)
An arbitrary amount of entanglement shared among nodes of a quantum network might be nondistillable if the nodes lack the information on the entangled Bell pairs they share. Making such a system distillable, which is called ...
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 ...
Prisoners’ dilemma in a spatially separated system based on spin–photon interactions
(MDPI, 2022-09)
Having access to ideal quantum mechanical resources, the prisoners’ dilemma can be ceased. Here, we propose a distributed quantum circuit to allow spatially separated prisoners to play the prisoners’ dilemma game. Decomposing ...
