Summary
In 2025, the quantum computing industry hit an inflection point, entering the fault-tolerant foundation era: Progress is now measured in error-corrected qubits and scaling, not raw physical qubit counts. As a result, both the path to quantum utility and the timeline to quantum risk have accelerated. Multiple analyses now place “Q-Day” (the point a quantum computer may break mainstream public-key crypto) around 2030. This compresses time to value, moving quantum computing from a someday dream to a five-year reality.
