The wrong question, answered honestly
Evidence boundary: any present-tense QNSI product wording below describes source-declared contracts, architecture targets, or vendor-run artifacts-not independently observed production behavior. Conformance artifacts prove only their stated algorithm scope. End-to-end production execution is NOT VERIFIED.
When will a quantum computer break encryption is the most-asked question in security, and the honest answer has not changed: nobody knows. Expert surveys place a cryptographically relevant quantum computer plausibly within 10 to 20 years, with some estimates sooner. That is a range, not a date - and no better date is coming.
Here is what the uncertainty does not change: whether your data is already exposed. That is decided by two numbers you can measure today, plus the one variable you actually control. This post gives you the math, the mandates that already fixed your deadline, and the fastest first mile available: QNSI.
Mosca's inequality: the decision without the date
Let X be the years your data must stay confidential, Y the years your migration will take, and Z the years until a machine that runs Shor's algorithm against real key sizes. If X + Y > Z, you are exposed - the data will still need its secrecy after the machine arrives.
You know X. A mortgage record: 25 years or more. A patient record: a lifetime. A defense document: decades. And Y is not small - previous cryptographic transitions took large organizations the better part of a decade. Put X + Y against any point in that surveyed 10-20 year range for Z, and for long-lived data the inequality already fails today.
Harvest-now-decrypt-later removes the last comfort. An adversary does not need the quantum computer to attack your long-lived data; recording your encrypted traffic and archives now and decrypting later is sufficient. The capture window is open at today's date, not the decrypt date.
The mandates already did this math for you
Regulators stopped waiting for a forecast. Executive Order 14412 (June 2026) fixes PQC deadlines for federal High-Value Assets - key establishment by 2030, signatures by 2031 - and orders CBOM minimum elements published within 270 days. CNSA 2.0 requires PQC in new national-security systems from January 2027, with the transition completing by 2033. DORA is already in force for EU financial entities. Whatever the quantum timeline turns out to be, the compliance timeline is now fixed - and your customers' security questionnaires will reach you before either.
QNSI collapses Y - the only variable you control
QNSI is the quantum-native security platform from HEOSSI. Its source connects a 87-algorithm migration catalog with key management, Vault, storage, search, transport, audit, and CBOM contracts. Each production claim remains bounded by the exact route, deployment, cryptographic effect, and independently reviewable evidence.
The first mile, concretely:
- Today - sign up Free Forever and create your first PQC keys the same day: ML-KEM for key establishment, ML-DSA or SLH-DSA for signatures, all enforced by a per-tenant crypto policy (default, strict, maximum, or government).
- Next - configure eligible inventory sources across 11 cloud-vendor connector families and 36 normalized source types, export CycloneDX, and review the source-defined migration readiness result with its evidence boundary.
- This month - move long-lived secrets into the quantum-safe vault, put SSE-X in front of long-horizon object stores, and set rotation policies and key algorithm upgrades so future improvements are configuration, not projects.
- This quarter - generate compliance evidence packs (SOC 2, HIPAA, GDPR, PCI DSS, ISO 27001, PDPA, MAS TRM) and show your reviewers dual-control maker-checker approvals on every crypto-policy change.
// pnpm add @heossihq/qnsi - free API key at cloud.qnsi.heossi.com
import { QnsiClient } from "@heossihq/qnsi";
const qnsi = new QnsiClient({ apiKey: process.env.QNSI_API_KEY! });
// Day one: a real post-quantum signing key

// Week one: readiness, scored from your live crypto inventory

const readiness = await qnsi.cryptoInventory.getReadinessScore(tenantId);Verify before you commit a dollar
None of the above is asserted on a slide. QNSI publishes live NIST ACVP conformance evidence at qnsi.heossi.com/verify/conformance - official vectors, re-runnable by you, no account required - and the 18 FIPS algorithms shared by our two independent implementations (native liboqs, cross-verified by noble) must agree before a result is trusted. The SDKs meet you in your language: TypeScript/Node (@heossihq/qnsi), Python (qnsi), Go, Rust (qnsi), JVM/Android (com.heossi:qnsi), plus a CLI and an MCP server.
Waiting is the only losing move
A better quantum forecast will not shrink your data's lifetime, and it will not shorten an enterprise migration; it will only tell you, too late, whether you started in time. Every month of delay is another month of traffic and archives harvested under keys already scheduled to fail. Start the migration clock now and the whole inequality moves in your favor - that is the entire strategy, and it is available this afternoon.
