چکیده
The present methods for obtaining the optimal LewenesteinSanpera decomposition of a mixed state are difficult to handle analytically. We provide a simple analytical expression for the optimal Lewenstein-Sanpera decomposition by using semidefinite programming. Specially, we obtain the optimal Lewenstein-Sanpera decomposition for some examples such as: Bell decomposable state, Iso-concurrence state, generic two qubit state in Wootters’s basis, 2 ⊗ 3 Bell decomposable state, d ⊗ d Werner and isotropic states, a one parameter 3 ⊗ 3 state and finally multi partite isotropic state.

A Two Level Approximation Technique for Structural Optimization
This work presents a method for optimum design of structures, where the design variables can he considered as Continuous or discrete. The variables are chosen as sizing variables as well as coordinates of joints. The main idea is to reduce the number of structural analyses and the overal cost of optimization. In each design cycle, first the structural response quantities such as forces, displac...
متن کاملGraph Partitioning and Semi-definite Programming Hierarchies
Graph partitioning is a fundamental optimization problem that has been intensively studied. Many graph partitioning formulations are important as building blocks for divide-and-conquer algorithms on graphs as well as to many applications such as VLSI layout, packet routing in distributed networks, clustering and image segmentation. Unfortunately such problems are notorious for the huge gap betw...

This lecture consists of two main parts. In the first one, we revisit Semi-Definite Programming (SDP). We show its equivalence to Vector Programming, we prove it has efficient membership and separation oracles and finally state a theorem that shows why Ellipsoid can be used to acquire an approximate solution of a semi-definite program. In the second part, we make a first approach to Combinatori...
متن کاملSDP Gaps and UGC Hardness for Multiway Cut, 0-Extension and Metric Labelling
The connection between integrality gaps and computational hardness of discrete optimization problems is an intriguing question. In recent years, this connection has prominently figured in several tight UGC-based hardness results. We show in this paper a direct way of turning integrality gaps into hardness results for several fundamental classification problems. Specifically, we convert linear p...
متن کاملEvaluation of relative entropy of entanglement and derivation of optimal Lewenstein-Sanpera decomposition of Bell decomposable states via convex optimization
We provide an analytical expression for optimal Lewenstein-Sanpera decomposition of Bell decomposable states by using semi-definite programming. Also using the KarushKuhn-Tucker optimization method, the minimum relative entropy of entanglement of Bell decomposable states has been evaluated and it is shown that the same separable Bell decomposable state lying at the boundary of convex set of sep...
