Quantum Computing Timelines 2025

Predictions from Around the Globe

There continues to be no consensus as to ‘when quantum computing’ by current day forecasters. So I thought it would be interesting to share the range of various sources who have written or spoken about the subject recently to help those making their own plans for quantum computing.

2025 is poised to be a transformative year for quantum computing, with breakthroughs in logical qubits, error correction, and early commercial applications. While fault-tolerant, large-scale systems are likely a few years away (2027–2030), advancements in hardware, quantum-AI integration, and PQC are setting the stage for significant impact. Predictions vary, with optimistic timelines (2–5 years for practical use) contrasted by more conservative estimates (15+ years), reflecting the field’s rapid but uncertain progress.
