Extremal Entangled Four-Qubit Pure States with Respect to Multiple Entropy Measures

  • 1. Department of Physics, Tsinghua University, Beijing 100084 (China)

Description

Four-qubit entanglement has been investigated using a recent proposed entanglement measure, multiple entropy measures (MEMS). We have performed optimization for the nine different families of states of four-qubit system. Some extremal entangled states have been found.
