Summary
Technical sovereignty is back in vogue as trust in global partners erodes. In quantum, that instinct translates into a push for a fully domestic, full-stack ecosystem across computers, sensors, and communications. The ambition is understandable given quantum’s strategic weight, but the reality is stubborn. The stack spans scarce isotopes, advanced materials, cryogenics or lasers, control electronics, specialized software, and hard-to-find talent. Today’s quantum supply chain is bespoke and scattered across the world, and even the WEF notes commercial quantum is inherently global.
The smarter path is quantum sovereign optionality. Instead of trying to own every layer, build leverage at key control points while partnering broadly. Prioritize domestic competence where security and IP are most sensitive, adopt open standards and interoperable interfaces, and multi-source critical components. For CISOs and cyber leaders, this translates to accelerating PQC and crypto agility, designing vendor-diverse and auditable architectures, and hardening the supply chain with transparency and assurance. Resilience will come from flexible choices and trusted ecosystems, not from isolation.
