Many-body localization protected quantum state transfer

Understand

In thermal phases, the quantum coherence of individual degrees of freedom is rapidly lost to the environment.

• Many-body localized (MBL) phases limit the spread of this coherence and appear promising for quantum information applications.
• However, such applications require not just long coherence times but also a means to transport and manipulate information.
• We demonstrate that this can be done in a one dimensional model of interacting spins at infinite temperature.
