Quantum computing is advancing rapidly. Innovations from Google, Microsoft, IBM and others are pushing the boundaries of not just the numbers of qubits but also their quality. We are well on our way to quantum computing being practical for real world problems. This also means we are also on the path to the existence of cryptanalytically relevant quantum computers (CRQCs) that can break a number of the algorithms much of modern security depends on. Opinions vary on the timeline of when a CRQC...
