On the Optimization and Self-Tensoring Construction of Nonlinear Entanglement Witnesses
Nonlinear entanglement witnesses constructed from multiple linear entanglement witnesses and multiple copies of quantum states have recently been proposed as a powerful tool for entanglement detection. In this work, we show, via an explicit counterexample, that the fineness of linear witnesses gener...
