Many body localization: Retaining quantum memory in interacting systems

Markus Müller
ICTP Trieste, Italy

For any kind of quantum technology, it is paramount to keep quantum many body systems in controlled out-of-equilibrium states, while maintaining their phase coherence. A major obstacle on this route is Nature's tendency towards equilibration and unwanted long range entanglement. 

An interesting way out may be offered by the phenomenon of many body localization, where thermalization is prevented by the complete suppression of transport. I will review the physics of the mechanisms at play, both with and without quenched disorder, and discuss implications for various types of quantum computation.
