A Practical Approach to SOS Relaxations for Detecting Quantum Entanglement
本文介绍了一个MATLAB工具箱PnCP，用于构造非完全正的正映射，并综述了优化和平方和松弛技术，以高效分类量子态纠缠。
Abstract This article introduces PnCP, a MATLAB toolbox for constructing positive maps which are not completely positive. We survey optimization and sum of squares relaxation techniques to find the most numerically efficient methods and establish some benchmarks for this construction. We also show how this package can be applied to the problem of classifying entanglement in quantum states.
