Quantum Computing Nears 3-5 Year Commercial Tests as Leaders Prioritize Post-Quantum Security
3 articles · Updated · Forrester · Aug 15
Summary
Quantum computing is moving from theory into engineering reality, with vendors making progress on scaling and error correction that could enable selective commercial use over the next 3–5 years.
That relevance will be narrow rather than broad: quantum systems are suited to optimization, molecular simulation and probabilistic modeling, while problems already handled well by classical computing are likely to stay there.
Hybrid architectures are central to that path, with quantum expected to handle only the hardest parts of a broader classical pipeline instead of becoming a standalone enterprise platform.
Post-quantum cryptography is the most urgent near-term priority, as hardware advances and more efficient versions of Shor’s algorithm could bring “Q-day” closer.
Forrester says industries such as life sciences, chemicals, finance, logistics, manufacturing and energy should start structured exploration now, while lower-fit sectors should monitor progress and avoid speculative spending.
