Beyond Harvest Now, Decrypt Later: Your Post-Quantum Game Plan, with Konstantinos Karagiannis

October 22, 2026 · 41 min

Show notes

What if the quantum threat everyone is preparing for isn't the one that will actually arrive first? Today, we're talking to Konstantinos Karagiannis, Senior Director of Quantum Computing Services at Protiviti. We explore why "harvest now, forge later" deserves a place next to "harvest now, decrypt later," how falling qubit estimates are sharpening the Q Day timeline and what that means for Bitcoin and Ethereum, and how leaders can build crypto-agility and lead by building while there's still time to act. If you want to hear more from Konstantinos, check out his show, The Post Quantum World Podcast. https://podcasts.apple.com/us/podcast/the-post-quantum-world/id1564148665
