SUMMARY:Quantum simulations of high energy physics models - Ignacio Cirac 
 (MPI - Garching)

CONTACT:Dr Joan Camps
DESCRIPTION:Many-body quantum systems are very hard to describe and simula
 te in\ngeneral\, since the dimension of the state space grows exponentiall
 y with the number of particles\, volume\, etc. Cold atomic systems may hel
 p us in that task\, as one can in principle engineer the interactions amon
 g the atoms to emulate many-body quantum problems. So far\, this possibili
 ty has been mainly addressed in the context of condensed matter systems\, 
 and a significant experimental effort is nowadays trying to pursue this go
 al. In this talk I will present some recent work where we have analysed ho
 w to use cold atomic systems to simulate simple high-energy models. In par
 ticular\, I will explain how lattice (compact) QED and  QCD in different d
 imension may be simulated. Time permitting\, I will also mention other eff
 orts to describe and simulate (classically) some of those problems using t
 ensor-network techniques\, as developed in the context of quantum informat
 ion theory.
