Scientists Unveil Quantum Entanglement Map in Protons

Scientists at Brookhaven National Laboratory have used quantum information science to map quantum entanglement among quarks and gluons inside protons, revealing a complex, dynamic system. This entanglement, occurring at incredibly short distances, affects the distribution of particles resulting from proton-electron collisions. The research, published in Reports on Progress in Physics, provides new insights into proton structure and lays the groundwork for future experiments at the Electron-Ion Collider, which will explore how nuclear environments impact entanglement.
