Manipulating Multi-qudit Entanglement Witnesses by Using Linear Programming
M. A. Jafarizadeh, G. Najarbashi, H. Habibian
A new class of entanglement witnesses (EWs) called reduction type entanglement witnesses is introduced, which can detect some multi-qudit entangeled states including PPT ones with…
Evaluation of relative entropy of entanglement and derivation of optimal Lewenstein-Sanpera decomposition of Bell decomposable states via convex optimization
M. A. Jafarizadeh, M. Mirzaee, M. Rezaee
We provide an analytical expression for optimal Lewenstein-Sanpera decomposition of Bell decomposable states by using semi-definite programming. Also using the Karush-Kuhn-Tucker o…
Exact calculation of robustness of entanglement via convex semi-definite programming
M. A. Jafarizadeh, M. Mirzaee, M. Rezaee
In general the calculation of robustness of entanglement for the mixed entangled quantum states is rather difficult to handle analytically. Using the the convex semi-definite progr…
Generalized qudit Choi maps
M. A. Jafarizadeh, M. Rezaeen, S. Ahadpour
Following the linear programming prescription of Ref. \cite{PRA72}, the Bell diagonal entanglement witnesses are provided. By using Jamiolkowski isomorphism, it is sho…
Investigation of continuous-time quantum walk by using Krylov subspace-Lanczos algorithm
M. A. Jafarizadeh, S. Salimi, R. Sufiani
In papers\cite{js,jsa}, the amplitudes of continuous-time quantum walk on graphs possessing quantum decomposition (QD graphs) have been calculated by a new method based on spectral…
Best separable approximation with semi-definite programming method
M. A. Jafarizadeh, M. Mirzaee, M. Rezaee
The present methods for obtaining the optimal Lewenestein- Sanpera decomposition of a mixed state are difficult to handle analytically. We provide a simple analytical expression fo…
Investigation of Continuous-Time Quantum Walk Via Modules of Bose-Mesner and Terwilliger Algebras
M. A. Jafarizadeh, S. Salimi
The continuous-time quantum walk on the underlying graphs of association schemes have been studied, via the algebraic combinatorics structures of association schemes, namely semi-s…
