Phase encoding in quantum key distribution (QKD) enables long-distance information-theoretic secure communication in optical fibers. We present a novel theoretical model characterizing errors from ...
Imagine encoding a secret message into a light signal that appears unpredictable—its complexity makes it nearly impossible to decrypt. This is the foundation of chaos-based secure communication.
Figure 1: Schematic of a quantum key distribution system. The transmitter (Alice) and receiver (Bob) generate composable keys by transmitting quantum states over an insecure quantum channel, ...
