Geometric measure of entanglement of multipartite mixed states
Shenglong Hu, Liqun Qi, Yisheng Song +1
The geometric measure of entanglement of a pure state, defined by its distance to the set of pure separable states, is extended to multipartite mixed states. We characterize the ne…

The geometric measure of entanglement of pure states with nonnegative amplitudes and the spectral theory of nonnegative tensors
Shenglong Hu, Liqun Qi, Guofeng Zhang
The geometric measure of entanglement for a symmetric pure state with nonnegative amplitudes has attracted much attention. On the other hand, the spectral theory of nonnegative ten…
