oshiba's research team has broken a new record for optical fiber-based quantum communications, thanks to a new technology called dual band stabilization. Researchers from Toshiba have successfully sent quantum information over 600-kilometer-long optical fibers, creating a new distance record and paving the way for large-scale quantum networks that could be used to exchange information securely between cities and even countries. Working from the company's R&D lab in Cambridge in the UK, the scientists demonstrated that they could transmit quantum bits (or qubits) over hundreds of kilometers of optical fiber without scrambling ....
