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 ...
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. ...
A parallel implementation: Real space Green's function technique
(Sage Publications, 2007-04)
We develop an MPI-based parallel algorithm to implement the real space Green's function technique for calculating the vibrational density of states corresponding to a solid. The Hamiltonian describing the interactions ...
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 ...
