**Zero-index nanophotonics, nonlinear optics, and quantum entanglement,**at

In these interactive lectures we explore how light can be manipulated at the nanoscale. We begin by describing optical propagation in ordinary materials and then show how materials can be engineered to achieve a refractive index of zero. These zero-index materials have remarkable properties and can be integrated in photonic circuits. We also give an introduction to nonlinear optics and discuss how zero-index materials can be used to accomplish phase matching in nonlinear optics and to obtain longer coherence times and lengths among entangled emitters or qubits.
