A Method and System for Hybrid Classical-Quantum Communication
The ultimate aim of a modern-day communications system is to transmit data using a high bandwidth link, while at the same time ensuring that the link is secure. High-bandwidth classical communications links are presently available and under continuous development the world over. In parallel, security can be achieved using a quantum link, with some simple systems commercially available. No solution exists to combine the two to realize the desired “fast and secure” link.
Wits researchers have developed a hybrid communication system that allows information to be sent both classically and in the quantum using the same link, realising a communication channel that is both fast and secure. The security is guaranteed through quantum laws and as such is fundamentally secure, unlike conventional
- Fundamentally secure communication
- Fast data transfer
