Quantum Advantage and National Security: From Lab to Supply Chain

Why quantum is now a board issue

Quantum technologies are exiting the lab: post-quantum cryptography standards are being set, quantum sensing is field-ready for mining and defense, and early error-corrected computing is on the 10-year horizon. Security, not speed, is the near-term economic catalyst.

Security first: PQC migration

Adversaries can store encrypted data now and decrypt later when quantum capability arrives. Canada’s critical infrastructure and banks should begin PQC transitions with crypto-agility: inventory algorithms/keys, prioritize high-value data, and deploy hybrid classical-PQC schemes.

Industrial advantage: sensing and materials

Quantum magnetometers, gravimeters, and RF sensors can improve exploration success rates and reduce false positives. In materials, quantum-assisted simulation could compress design cycles for batteries, fertilizers, and catalysts—core Canadian export chains.

What leaders can do

  1. Launch a crypto-inventory: map algorithms, keys, lifetimes, and vendors; build a PQC cutover plan.
  2. Stand up a quantum risk committee reporting to the board.
  3. Pilot quantum sensing with mining, energy, and aerospace partners.
  4. Invest via consortia: share IP and cost in pre-competitive research.
  5. Require crypto-agility in all new procurements (banking, payments, device firmware).

Arcus Insight: Quantum advantage will show up as security resilience and incremental sensing wins long before universal quantum computing. Treat PQC as mandatory cyber hygiene—and the rest as targeted R&D sprints.
