Recent rapid progress in many-particle quantum physics has been driven by a wide variety of new experiments, by theoretical insights into gravity and field theory (like the AdS/CFT duality), and by the prospect of constructing a universal quantum computer. In the midst of this boom, we are also looking at old problems in new ways, using concepts from quantum information. However, a general framework is still lacking. I will argue that tensor networks provide a powerful and unifying language for quantum matter and I will show how they shed light on problems ranging from low-temperature states of strongly interacting electrons to the emergence of gravity from microphysics.
