We present a method for multipartite entanglement purification of any stabilizer state shared by several parties. In our protocol each party measures the stabilizer operators of a quantum errorcorrecting code on his or her qubits. The parties exchange their measurement results, detect or correct errors, and decode the desired purified state. We give sufficient conditions on the stabilizer codes...

This manuscript introduces various notions of k-locality of stabilizer codes inherited from the associated stabilizer groups. A choice of generators for the group leads to a Hamiltonian with the code in its groundspace, while a Hamiltonian holding the code in its groundspace might be called effective if its locality is less than that of a natural choice of generators (or any choice). This paper...

In this paper, the design of a PID type stabilizer is investigated using Genetic algorithms. The proposed stabilizer is applied to a single machine infinite bus system subjected to a load disturbance. Comparison with Conventional lead-lag Power System Stabilizer (CPSS) and other design methods of PID stabilizers shows the out performance of the proposed design. Furthermore, the proposed stabili...

in suspension polymerization, particle size distribution of polymer is the outcome of dynamic equilibrium between the break up and coalescence phenomena. the rates of break up and coalescence and consequently polymerization stability depend on several parameters, the most important of which are type and concentration of stabilizer. in this study, the effects of type and concentration of stabili...

Purpose: The aim of the work was a numerical and experimental analysis of spine’s transpedicular stabilizer on lumbar part of spine. The result of the analysis was determination of displacements of the stabilizers’ elements. Design/methodology/approach: To define numerical characteristic of the lumbar spine – transpedicular spine stabilizer system, the finite element method was applied. Geometr...

The power system stabilizer is used to damp out the low frequency oscillations that improve the small signal stability of the power system. If ignored these low frequency oscillations may lead to cascaded failure of the complete power system. This paper presents the comparative study of conventional power system stabilizer (CPSS) with newly proposed Adaptive Fuzzy Logic Controlled Power System ...

This paper investigates the relation between linear codes and the stabilizer in GL2(C) of their weight enumerators. We prove a result on the finiteness of stabilizers and give a complete classification of linear codes with infinite stabilizer in the non-binary case. We present an efficient algorithm to compute explicitly the stabilizer of weight enumerators and we apply it to the family of Reed...

We present a new approach to simulate arbitrary quantum circuits on a classical computer. Our technique generalizes the stabilizer formalism, the underpinnings of the Gottesman-Knill theorem, to include arbitrary states and arbitrary quantum operations. The core of our approach is a novel state representation combining the density matrix and stabilizer representations. Obviously, not all simula...
