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 ...
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 ...
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 ...
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 ...
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. ...
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 ...
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 ...
Deterministic local doubling of W states
(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, ...
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 ...
