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. ...
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 ...
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 ...
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 ...
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. ...
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 ...
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 ...
