Resumen:
The notion of distance in Hilbert space is relevant in many scenarios. In particular, distances" between quantum states play a central role in quantum information the- ory. An appropriate measure of distance is the quantum Jensen Shannon divergence (QJSD) between quantum states. Here we study this distance as a geometrical measure of entanglement and apply it to diĀ®erent families of states.
