Scaling of entanglement entropy and superselection rules
I. Klich, L. S. Levitov
Particle number conservation in fermionic systems restricts the allowed local operations on bi-partite systems. We show how this restriction is related to measurement entropy of pa…

Quantum Noise as an Entanglement Meter
Israel Klich, Leonid Levitov
Entanglement entropy, which is a measure of quantum correlations between separate parts of a many-body system, has emerged recently as a fundamental quantity in broad areas of theo…
