WebApr 12, 2024 · Another disadvantage of quantum cryptography devices is their limited range. The quantum key distribution approach is only effective over short distances, typically a few hundred kilometers. This makes it harder to employ quantum cryptography to secure communication lines over extended distances. WebThe advent of a quantum computer powerful enough to process the current public keys algorithms will destroy our cybersecurity infrastructure. This is often referred to as the Y2Q (Year to Quantum) by reference to the famous Y2K bug. Today, Y2Q is widely expected within a short decade.
