Post-Quantum Cryptography and Migration

Q-Day — when quantum computers crack all encryption — is coming. Quantum eMotion COO John Young breaks down the pros and cons of what's to come.

What We Discuss with John Young:

• Q-Day is the looming moment when quantum computers become powerful enough to break current encryption — rendering bank accounts, medical records, government secrets, and critical infrastructure vulnerable not through hacking, but through raw computational power that can solve in minutes what would take today's computers longer than human civilization has existed.
• "Harvest now, decrypt later" is already happening. Adversaries are collecting encrypted data today, storing it like a time capsule, waiting for quantum computers to mature so they can unlock secrets that were meant to stay buried forever — meaning today's sensitive communications could become tomorrow's exposed vulnerabilities.
• Quantum computers aren't just faster classical computers — they operate on fundamentally different physics — using qubits that can exist in multiple states simultaneously, allowing them to explore countless possibilities at once rather than checking solutions one by one, which is what makes them so dangerous to current encryption methods.
• The transition to quantum-safe encryption is a massive, slow-moving crisis. Large institutions with decades of layered encryption systems face years of retrofitting, while startups can build quantum-resistant from day one, creating a dangerous gap where critical infrastructure remains exposed during the changeover.
• The same technology threatening our digital security also promises extraordinary breakthroughs. Quantum computing could deliver miracle drugs, better batteries, climate solutions, and new materials, so the path forward isn't fear but preparation: organizations should begin transitioning to quantum-resistant algorithms now while the benefits still outweigh the risks.
• And much more...
