Researchers Build an _ Unhackable

Toshiba researchers have successfully sent quantum information over 600 kilometers of optical fiber, setting a new distance record and paving the path for large-scale quantum networks that might be used to securely share data across cities and even countries.

Thanks to a new technology that stabilizes the environmental fluctuations occurring in the fiber, the scientists demonstrated that they could transmit quantum bits (or qubits) over hundreds of kilometers of optical fiber without scrambling the fragile quantum data encoded in the particles, working from the company’s R&D lab in Cambridge, UK.
