Quantum networks are at the center of recent advances in quantum information, communication, and computation. These networks can be used to simulate complex materials and study the emergence of order in many-body systems. To explore new capabilities on the frontiers of engineered coherent matter that these systems might provide, the National Academies of Sciences, Engineering, and Medicine Condensed Matter and Materials Research Committee held a hybrid in-person and online workshop in Washington, DC on October 3, 2024. The workshop reviewed the rapidly emerging implementations of these systems and their relation to fundamental problems and applications in condensed matter physics, materials science, and quantum information. This publication summarizes the presentations and discussion of the workshop.

Elementary particle physics reflects the human quest to understand the basic building blocks of nature and the rules that govern the physical world. This quest has led not only to critical scientific advancements and technology breakthroughs, but also to the development of essential technologies enabling new medical treatments, productive techniques in manufacturing, and enhanced capabilities in quantum computing, as well as ancillary benefits such as the precursor to the World Wide Web, which was created to manage the enormous data flows at CERN. At the request of the Department of Energy and the National Science Foundation, this report explores long-term goals and future ambitions for particle physics. Elementary Particle Physics: The Higgs and Beyond presents a bold 40-year vision for the field and highlights critical actions necessary to make this vision reality. The recommendations of this report will guide support and investments to maintain U.S. leadership in particle physics and move the field forward.
