Localizable Entanglement and Valence Bond States

by Ignacio Cirac (Max Planck Institute fuer Quantumoptik, Garching, Germany)

ABSTRACT

Much of the current effort in Quantum Information Theory is devoted 
to the description and quantification of the entanglement contained 
in quantum states, since this intriguing property of Quantum 
Mechanics is the basic resource of most of the applications in this 
field, including quantum communication and computation. In this talk 
I will introduce a new notion of entanglement which captures the idea 
of how this property can be localized in small subsystems by 
performing measurement in the rest of the system. I will also show 
how this notion allows to detect hidden orders in spin systems at 
zero temperature, and how it behaves in quantum phase transitions. 
Finally, I will show how these ideas may help to develop simulation 
schemes for spin chains and lattices.
