Quantum Internet Achieves 10Gbps Over 5,000km

A joint research team has demonstrated a quantum communication link sustaining 10Gbps of entangled-photon throughput across a 5,000-kilometer relay network, a tenfold jump over the previous record. The breakthrough hinges on a new generation of cryogenic quantum repeaters that preserve entanglement fidelity across far longer distances than before.

The achievement brings a globally distributed, provably unhackable quantum internet meaningfully closer, with financial institutions among the first expected to adopt the technology for ultra-secure transactions.
