The team at Google Quantum AI has published a clear roadmap that outlines the sequential milestones for creating an error-corrected quantum computer and delivering real-world applications.
The milestone journey
-
Google frames its roadmap around the development of a long-lived logical qubit (“Milestone 2”) and then scaling toward large, error-corrected systems.
-
The roadmap emphasises transition from laboratory experiments (quantum supremacy) to meaningful applications (simulation, optimization, cryptography) — bridging the gap between hardware and utility.
Why this is a strategic inflection point -
For companies building on quantum-aware software and infrastructure (like PostQuantumApps), this roadmap signals where the hardware and software converge. The “when” is becoming clearer.
-
It invites you to ask: which stage are my offerings targeting? Are they aligned with near-term milestones (logical qubit scaling) or the longer-term (full fault-tolerance)?
Implications for strategy -
Map each of your app modules to one of these stages. For example: “Pre-fault tolerant quantum integration”, “hybrid classical-quantum pipeline”, “quantum safe cryptography layering”.
-
Emphasize in your messaging that you are “quantum-aware” and “preparing for the next generation of quantum hardware” — that helps position the brand.
Bottom line
Quantum computing is no longer just an academic pursuit — it’s becoming an engineering discipline with milestones, architectural constraints and commercial-grade timelines. Aligning with this shift now increases the odds you won’t be “left behind in the surf”.
