In an analysis published by Bitcoin Magazine, Brandon Black argues that the threat of cryptographically relevant quantum computers (CRQC) to Bitcoin is an exaggerated fear. Black states there is no evidence a CRQC will be built within a decade, and it remains uncertain if such a machine will ever be developed. The article highlights the current limitations of quantum computing technology, noting that despite significant investment, the path to stable, low-error qubits for breaking cryptographic systems is far from clear. Black suggests that many recent advancements are either purely mathematical or represent restarts in various candidate technologies, rather than linear progress towards a viable CRQC.
