Welcome to the companion website for the upcoming Harvard Radcliffe Institute’s private program, “Entanglement Explored: Quantum Materials in Equilibrium and Beyond.” We are very excited for this event, taking place on May 1-2, 2025, and we look forward to seeing everyone soon.  Please feel free to explore this website.  We will strive to make sure that the most up-to-date information is installed.  Thank you. 

Executive Summary

Many-body entanglement is a pivotal element for the emergence of extraordinary macroscopic quantum phenomena, including superconductivity, topological phases, and quantum spin liquidity. Once merely viewed as a peculiar ‘spooky action at a distance,’ entanglement has evolved into an invaluable tool for distinguishing quantum from ordinary matter. Although its measurement and manipulation in macroscopic systems poses significant challenges, recent breakthroughs indicate that modern experimental techniques may now allow us to directly probe entanglement in quantum materials. This progress is crucial as interrogating quantum entanglement paves the way to uncovering new categories of quantum phenomena and states of matter. Our Accelerator Workshop aims to bring together experts in diverse areas encompassing condensed matter physics, quantum information sciences, and philosophy, and with the goal to overcome traditional barriers in the study of quantum mechanics and entanglement. This interdisciplinary effort seeks to establish a new research field, broadly defined as “entanglement spectroscopy” of quantum materials, and to deepen our understanding of macroscopic quantum phenomena within the realm of everyday human experience. We plan to devise experiments interrogating entanglement in quantum materials by using quantum metrological concepts, while merging theoretical insights, philosophical perspectives on quantum mechanics, and the intricacies of practical measurements. By establishing a fresh conceptual framework for our understanding of how matter works, this workshop is set to contribute to the definition a new branch of contemporary physics.
