Measuring von Neumann entanglement entropies without wave functions
T. Mendes-Santos, G. Giudici, R. Fazio +1
We present a method to measure the von Neumann entanglement entropy of ground states of quantum many-body systems which does not require access to the system wave function. The tec…

Dynamics of Entanglement in One-Dimensional Spin Systems
L. Amico, A. Osterloh, F. Plastina +2
We study the dynamics of quantum correlations in a class of exactly solvable Ising-type models. We analyze in particular the time evolution of initial Bell states created in a full…
