Q-Day is a procurement date
The quantum computer is not the deadline. The purchase order is.
01In one sentence
Europe and the United States are putting dates on the quantum threat — 2027, 2030, 2031, 2035 — and the value is moving from encrypting data in transit to proving who signed it, which chip holds the key, and keeping that true through years of updates.
04Three numbers
05What to watch
| 29 September 2026 | The EDF call on quantum-secured tactical networks closes; three entities from three member or associated countries. Ukraine’s association, pending in March, is now confirmed.31,32,37 |
| Early 2027 | First quantum-safe certificates expected on the public web; Let’s Encrypt targets production Merkle Tree Certificates in 2027.16,38 |
| Standards | The Falcon signature standard (FIPS 206) is still “in development” at NIST. Anything built on it is built on a draft.17 |
| Financing | PQShield (Oxford) and CryptoNext (Paris) last raised in June 2024 and November 2023. In our judgement both are likely to be in the market; neither has said so.33,34 |
