Quantum encryption faces several challenges in implementation, primarily rooted in its complexity and the need for specialized hardware. Deploying quantum-resistant algorithms requires substantial changes to existing encryption infrastructures. Furthermore, maintaining the quantum key distribution securely over long distances is still an evolving area of research. Technical barriers, such as noise in quantum systems, can hinder the accuracy of the transmissions. Additionally, there is a shortage of professionals with the necessary expertise in quantum technologies, which contributes to slow adoption rates and limited practical applications in secure communications.
