"Breakthrough: Quantum Data Stored and Retrieved for Groundbreaking Internet Security"

Researchers have developed a system of atomic processing nodes that can produce, store, and retrieve quantum information, a crucial step towards creating a quantum-based network. This system involves a semiconductor quantum dot emitting single photons and a cloud of hot rubidium atoms serving as quantum memory, with a laser controlling the storage and release of photon states. While still in the prototype stage, this advancement could pave the way for stable quantum networks, addressing previous challenges in linking photon sources and processing nodes.
