Quantum secure communications refer to a method of transmitting information that leverages the principles of quantum mechanics to ensure security against eavesdropping. By using quantum key distribution (QKD), this communication method allows two parties to share a secret key that is theoretically immune to interception, as any attempt to observe the quantum state of the key would disrupt it and alert the parties involved. This capability makes quantum secure communications a crucial aspect of enhancing cybersecurity in today's digital world.
