#### 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 ...

#### 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 ...

#### 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 ...

#### Fusing multiple W states simultaneously with a Fredkin gate

(Amer Physical Soc, 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 ...

#### 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 ...

#### 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 ...

#### Phase damping destroys quantum Fisher information of W states

(Elsevier Science Bv, 2014-09-05)

We study the quantum Fisher information (QFI) of W states in the basic decoherence channels. We show that, as decoherence starts and increases, under i) depolarizing, QFI smoothly decays; ii) amplitude damping, QFI first ...

#### Constructing quantum logic gates using q-deformed harmonic oscillator algebras

(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 ...

#### 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. ...
