A Note on Quantum Separability
arXiv:quant-ph/0311184
Abstract
This short note describes a method to tackle the (bipartite) quantum separability problem. The method can be used for solving the separability problem in an experimental setting as well as in the purely mathematical setting. The idea is to invoke the following characterization of entangled states: A state is entangled if and only if there exists an entanglement witness that detects it. The method is basically a search for an entanglement witness that detects the given state.
