Fiber Optic Cables and Quantum Communication
The discovery, published in the journal Optica, introduces the new possibility of combining quantum communication with existing Internet cables — greatly simplifying the infrastructure required for for advanced sensing technologies or quantum computing applications. Unlike binary bit based digital communications, quantum information is transmitted in qubits, which can store multiple values at once, making quantum communications more secure. A new integrated chip demonstrates how quantum networks could communicate using today's internet protocols over existing commercial fiber-optic cables. In a groundbreaking experiment, engineers at the University of Pennsylvania successfully extended quantum networking beyond the laboratory by. The system, known as Xinghan-2, was detailed in the journal Nature Photonics on May.
