  The last two decades have seen the emergence of stunning interconnections
among various previously remotely related disciplines such as condensed matter,
nuclear physics, gravity and quantum information, fueled both by experimental
advances and new powerful theoretical methods brought by holographic duality.
In this non-technical review we sample some recent developments in holographic
duality in connection with quantum many-body dynamics. These include insights
into strongly correlated phases without quasiparticles and their transport
properties, quantum many-body chaos, and scrambling of quantum information. We
also discuss recent progress in understanding the structure of holographic
duality itself using quantum information, including a "local" version of the
duality as well as the quantum error correction interpretation of quantum
many-body states with a gravity dual, and how such notions help demonstrate the
unitarity of black hole evaporation.
