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 ...
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 ...
Quantum fisher information of several qubitsin the superposition of A GHZ and two W stateswith arbitrary relative phase
(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 ...
Freezing optical rogue waves by Zeno dynamics
(Elsevier Science BV, 2018-04-15)
We investigate the Zeno dynamics of the optical rogue waves. Considering their usage in modeling rogue wave dynamics, we analyze the Zeno dynamics of the Akhmediev breathers, Peregrine and Akhmediev-Peregrine soliton ...
