Quantum networks are closer to reality - The Verge
"Like the internet we know, quantum networks send information carried by light — in this case, quantum-entangled photons. But they need “repeaters” to prevent those photons from scattering across long distances, as light is wont to do, and the repeaters have to be able to send the photon without breaking its entanglement and modifying the information.
Harvard and AWS say the experimental nodes use cavities in diamonds that “trap light and force it to interact with quantum memories.” These nodes can be mass-produced with existing nanofabrication technology. During their experiments, the team took a qubit encoded into a photon and bounced it off a quantum memory in a Harvard lab." https://www.theverge.com/2024/5/16/24158365/quantum-computing-network-aws-amazon-harvard
