Quantum random number generation

On-silicon quantum random number generation (QRNG) — true, non-deterministic entropy from a quantum physical process (avalanche/tunnelling noise in CMOS-compatible silicon) — plus the wider quantum-security IC layer is a real, policy-pulled market.

The callPost-quantum migration and the EU Cyber Resilience Act make certified randomness a legal line item, but the secure-element vendors build entropy onto their own chips.

Fig. 1The balance. Drivers and catalysts against restraints, each block sized by its weight; catalysts hang dashed because they have not happened yet, sized by their odds. It tips toward the restraints.
  1. D1Post-quantum algorithms roll out and the Cyber Resilience Act makes security a legal obligation for every connected product, so every key's randomness becomes a compliance item.
  2. D2Ring oscillators and jitter are classical circuits whose randomness is assumed, and can be biased by temperature, voltage or an attacker; quantum entropy proves it from physics.
  3. R1The secure-element vendor absorbs the block: ID Quantique ships inside Samsung Knox, SEALSQ got its own block validated in May 2026.
  4. R2A software jitter RNG matches ID Quantique's Quantis on SP 800-90B, so certifiers and buyers may settle on good-enough classical sources for volume products.
  5. C1The Cyber Resilience Act's main obligations apply to every connected product, making a certifiable entropy source a line item for every maker.11 Dec 2027

  • 22 Jun 2026True-randomness-on-silicon (QRNG) is a small but policy-pulled security market — the post-quantum-crypto transition and European quantum-comms sovereignty are the why-now. The seed question is not "is quantum randomness better" (it is) but whether a certifiable, cheap CMOS entropy source can out-compete both the specialist incumbents and a good-enough on-chip TRNG.
