Universality in volume-law entanglement of scrambled pure quantum states

Universality in volume-law entanglement of scrambled pure quantum states

The entanglement in a quantum system between a small region and the surrounding environment contains details about the whole state. Nakagawa et al. find a formula for the entanglement entropy of a class of thermal-like states and show that it can be applied more broadly to identify equilibrating sta...
