"Adding Noise for Completely Secure Communication"

The use of quantum computers by hackers poses a threat to the security of current communications systems. Quantum computers' quantum-mechanical properties will allow them to perform calculations much faster than today's computers. The speed at which quantum computers will calculate will deem current encryption algorithms obsolete. Therefore, researchers are working to develop new encryption methods that involve the principles of quantum mechanics. A team of physicists has set up the theoretical foundation for a communication protocol that ensures privacy and security. The protocol offers protection against hackers in possession of quantum computers through the addition of artificial noise. This article continues to discuss how the new protocol guarantees secure communication.
