Quantum cryptography uses the principles of quantum mechanics to secure data transmission. It relies on the behavior of particles at the quantum level, primarily focusing on the properties of photons. Unlike traditional cryptographic methods, which can be vulnerable to hacking, quantum cryptography offers a way to detect eavesdropping.In this system, any attempt to intercept or measure the quantum states of transmitted particles alters their state, thereby revealing the presence of an unauthorized observer. This property ensures that communication can be made secure, enabling parties to share information with a high level of confidence.As cryptocurrencies continue to grow, the potential for quantum computers to break existing cryptographic algorithms raises concerns. Developing quantum-resistant protocols becomes crucial to protect user data and transactions. By integrating quantum cryptography, crypto networks could safeguard against future threats posed by advances in quantum computing technology, ensuring continued security and trust.
