The Internet of Things (IoT) is revolutionizing the industrial revolution by connecting objects through communication protocols and sensors. However, the integration of these networks with the traditional Internet poses potential risks. Researchers are developing post-quantum cryptography (PQC) to address these issues. Quantum computing, including entanglement trading and the no-cloning theorem, is essential for creating safe cryptocurrencies. Pre-quantum security solutions for IoT applications should prioritize quantum-safe encryption. Traditional cryptosystems are at risk due to quantum computing's resource-constrained nature. Quantum entanglement allows for odd correlations between states, leading to new protocols for applications like quantum teleportation, superdense coding, and cryptography. The no-cloning theorem is the foundation for various quantum technologies.
