U.S. invests $2 billion in quantum computing while post-quantum defense lags
In brief
- Commerce Department awarded $2 billion to nine quantum companies; IBM received $1 billion, GlobalFoundries $375 million
- Post-quantum cryptography defense lacks comparable government funding despite critical need against future quantum computers
- Industry-wide migration to post-quantum systems requires coordination regulators and protocol communities have deferred
The offense outpaces the defense
IBM is receiving $1 billion to build a quantum-grade superconducting wafer foundry. GlobalFoundries is getting $375 million for a multi-architecture fab. The remaining $636 million is split across seven companies building quantum computers across superconducting, trapped ion, photonic and neutral-atom modalities.
The Commerce Department believes quantum computing is beyond the experimental phase. It wants to win the race to a cryptographically relevant quantum computer before adversaries do. But here's the imbalance: the defense side has no comparable backer.
To defend against a cryptographically relevant quantum computer, post-quantum cryptography is needed. Google's quantum researchers have spent the last twelve months publishing increasingly aggressive resource estimates for breaking elliptic curve cryptography. The timeline is tightening. Experts recommend that migration to post-quantum cryptography should begin immediately.
The coordination trap
The real problem isn't money—it's coordination. The issue with post-quantum defense is that everyone needs to adopt the solution at once. This is more of a coordination problem than a financial hurdle.
Bitcoin illustrates the scale of the challenge. Securing Bitcoin requires every wallet, custodian, exchange and long-dormant address to move to a new cryptographic system together. Partial adoption doesn't work. Partial migration is partial protection.
The most exposed institutional holders have been waiting for coordination work to happen before migrating to post-quantum cryptography. Yet no funded entity has taken on that role at the scale Bitcoin requires.
A three-way race compresses the timeline
The U.S. move sparked immediate responses from rivals. The day after the U.S. announcement, Emmanuel Macron committed €1 billion to France's quantum strategy and called for Europe to "change the scale" of investment, naming the U.S. and China as its competitors.
China had already moved. China had routed roughly $17.5 billion through three regional venture funds before the U.S. announcement landed. Now the U.S. move gives Beijing the political cover to authorize another round.
This is what a three-way industrial-policy race looks like, and it just compressed everyone's planning horizon. The asymmetry is stark: offense gets $2 billion and political momentum. Defense gets deferred coordination work and no clear backer.
