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 ...

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.

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 ...

The future battlespace presents advanced adversarial Electronic Warfare (EW) capabilities that could contest the United States in all domains. A peer or near-peer adversary will employ multiple ...
