Quantum memories displaying identical performance at room temperature: step towards quantum repeaters and quantum internet
"built quantum internet testbed by demonstrating foundational quantum network measurement employing room-temperature quantum memories... room temperature makes it faster, cheaper... storing photons with a user-defined storage time shows time synchronization of photons’ retrieval as required for quantum repeater... distributes entanglement over twice the distance that single source of entangled photons could achieve... spread entanglement over 100's km by stitching together several repeaters"
