Learning how to create, study, and manipulate highly entangled states of matter is key to understanding exotic phenomena in condensed matter and high energy physics, as well as to the development of useful quantum computers. In this talk, I will discuss recent experiments where we demonstrated the realization of a quantum spin liquid phase using Rydberg atoms on frustrated lattices and a new architecture for quantum information processing based on the coherent transport of entangled atoms through a 2D array. Finally, I will describe how combining these advances with modern photonic control tools could open a broad range of possibilities for building truly scalable quantum systems, enabling powerful applications in quantum simulation and information processing.
