Quantum entanglement is the origin of both the weirdness associated with quantum systems and the power of many proposed quantum technologies. While largely studied in the the context of a few particles, recent work has emphasized its importance in macroscopic systems, such as electronic solids with many interacting particles. I will discuss examples where quantum entanglement has helped us classify and discover new topological phases of matter, which may have applications to future quantum devices. Finally, I will review related theoretical progress on a remarkable new quantum system - two sheets of graphene, rotated relative to one another by just one degree - where a variety of states including superconductivity have been observed.
