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.
Quantum secure direct communication (QSDC) is a type of quantum communication that directly employs quantum states as information carriers for secure communication. It has the characteristics of ...
Free-space quantum secure direct communication (QSDC) does not require the laying of optical fibers, which can effectively prolong the transmission distance and break the limitation of terrain. It is ...
