Quantum computing technology is advancing faster than organizational strategy, cybersecurity, and regulatory frameworks can adapt. Quantum How is a strategic guidebook designed to help boards and executive leaders understand what is coming—and what must be done now to ensure resilience, competitiveness, and national leadership.
There is great opportunity. Quantum computing will enable transformational advances in finance, logistics, climate science, advanced materials, pharmaceuticals, and national security. Organizations that begin capability building early will secure a decisive strategic advantage. While late movers will be left competing for scant resources.
There is danger. Digital trust, cryptography, and mission-critical systems across the public and private sectors all rely on mathematical assumptions that will be challenged by quantum computing. The risks are not hypothetical: the Harvest Now/Decrypt Later (HNDL) and Trust Now/Forge Later (TNFL) threats are already active, with adversaries already collecting data for future attacks. For organizations with long-lived or high-value data, this creates immediate exposure.
Quantum How provides leaders with:

"Becoming quantum safe is a strategic goal that organisations need to consider now. This guide will help executives and board members to start planning for the transition to post-quantum cryptography. This is a major overhaul that will need careful planning and coordination, because cryptography is a critical component of any IT asset. "

"The opportunity to join an ecosystem where government, investors, scientists and businesses work together to leverage the Canadian leadership advantage to solve some of the most complex problems of our time and drive real ROI for business and sustainable growth for Canadians is now. An opportunity we must capture."

CEO, Applied Quantum & Author, PostQuantum.com
"What impresses me most is how comprehensive this guide is: in a single document it takes a board from why quantum matters, through threat models and post‑quantum cryptography, Canada’s position, and sector impacts, all the way to a concrete multi‑year roadmap and the right questions to ask management."
