Extraction of Pure Entangled States from Many Body Systems by Distant Local Projections
J. Molina-Vilaplana, H. Wichterich, V. E. Korepin +1
We study the feasibility of extracting a pure entangled state of non-complementary, and potentially well separated, regions of a quantum many-body system. It is shown that this can…

Scaling of entanglement between separated blocks in spin chains at criticality
H. Wichterich, J. Molina-Vilaplana, S. Bose
We compute the entanglement between separated blocks in certain spin models showing that at criticality this entanglement is a function of the ratio of the separation to the length…
