Introduction
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. What new capabilities might these systems provide, and what new physics can we learn? What new devices can we create, what are they good for, and why are they worth investing in to build?
On October 3, 2024, the National Academies of Sciences, Engineering, and Medicine’s Condensed Matter and Materials Research Committee held a hybrid in-person and online workshop in Washington, DC, on the frontiers of engineered coherent matter and systems.1 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 (see Appendix A).

ORGANIZATION OF THE PROCEEDINGS
This Proceedings of a Workshop summarizes the presentations and discussions that occurred at that workshop.2 Its structure mirrors the structure of the workshop itself, with the following five chapters devoted to recapitulating the workshop’s four sessions and final wrap-up. Each of the four sessions had a panel of presenters who gave prepared remarks followed by a discussion session in which that session’s panelists, presenters from other sessions, and audience members asked and answered questions.
Chapter 2 is an introduction to and an overview of the field of engineered coherent quantum matter and systems. It sets the stage for the rest of the proceedings. Chapter 3 is focused on solid-state platforms, including the use of arrays of superconducting qubits for quantum emulation, work with nitrogen–vacancy centers in diamond anvil cells, and quantum states in semiconductors. Chapter 4 examines a variety of other platforms beyond solid-state platforms, including optical cavities, photonic networks, and ultra-cold atoms. Chapter 5 examines quantum information dynamics, including monitored quantum circuits and synthetic topological systems. Chapter 6 recounts the workshop’s wrap-up session.
