From Algorithms to Action: Google’s Quantum Roadmap & Why It Matters 🚀
On 14 November 2025, Google’s Quantum AI team unveiled a new five-stage framework designed to steer quantum computing from pure theory toward real-world impact. This isn’t just about more qubits — it’s about doing stuff with them.
1. The five stages in a nutshell:
-
Discovery of new quantum algorithms
-
Identifying hard problem instances
-
Demonstrating quantum advantage in real-world tasks
-
Optimising for implementation
-
Deploying quantum solutions into production workflows
Google warns that many efforts still linger too long in the early stages and calls for stronger investment and collaboration.
2. Why this matters for businesses & engineering teams:
It signals a shift: from “we built a 120-qubit chip” to “we solved a real supply-chain optimisation with it.” For companies like PostQuantumApps, that means ecosystem maturity is approaching — quantum + classical hybrid solutions become more plausible.
3. What you should keep on your radar:
-
Open-source toolchains paired with quantum hardware
-
Cross-discipline partnerships (algorithm ↔ application)
-
Metrics that focus on usefulness, not just “qubit count”
-
For us: QA + PQ-cryptography readiness arriving sooner
Conclusion:
Google’s roadmap emphasises that quantum computing is no longer just the future; the future is now. Organisations should ask which stage they’re at — are they still discovering, or moving toward deployment? The difference will shape competitive advantage.
