Quantum security is a research area focused on developing and enhancing security protocols and systems that are resistant to attacks from quantum computers. Quantum computers have the potential to break conventional cryptographic algorithms used for secure communication and data protection, posing a significant threat to current cybersecurity measures. Researchers in quantum security are exploring new cryptographic techniques, such as quantum-resistant encryption and quantum key distribution, to ensure data confidentiality, integrity, and authentication in the presence of quantum threats. This field is essential for establishing secure communication in a future where quantum computing becomes more prevalent.
