Long-range quantum entanglement is now being recognized

as a key characteristic of many novel states of quantum matter.

The description of this entanglement requires the introduction

of emergent “gauge fields”, much like those found in Maxwell’s

theory of light. I will highlight some recent experiments on the

copper-based high temperature superconductors, and interpret

them using theories of emergent gauge fields.
