A geometric measure for the entanglement of a unit length tensoris given by −2log2∥T∥σ, wheredenotes the spectral norm. A simple induction gives an upper bound of (k−1)log2(n) for the entanglement. We show the existence of tensors with entanglement larger than klog2(n)−log2(k)−o(log2(k)). Friedland and Kemp (Proc. AMS, 2018) have similar results in the case of symmetric tensors. Our techniques give improvements in this case.
