Many countries have created national quantum strategies in order to centralize or coordinate quantum research, innovation, commercialization, and talent development in their countries. This chapter comparatively analyzes four national quantum strategies from Canada, Denmark, the Netherlands, and the UK. Each country embraces its own model for quantum strategy, with some favoring large, generative investments, while others pursue more decentralized or additive investments. The overall financial commitments may seem large in the aggregate but constitute a modest per annum spending. Countries that have yet to create their own national strategy can learn from the diverse models for building quantum ecosystems.
