The Post-Quantum World

Konstantinos Karagiannis hosts this biweekly series through Protiviti, and the angle is different from most quantum podcasts. The focus here is squarely on business impact. How will quantum computing affect cybersecurity? What should enterprises be doing right now to prepare? When does post-quantum cryptography actually matter? These are the kinds of questions that get serious treatment across 121 episodes. The guest list is impressive. Karagiannis brings on researchers from organizations like NTT, experts in quantum-safe cryptography, and people working on real deployment timelines. He has a knack for keeping conversations accessible even when the subject matter gets dense. The show manages to bridge the gap between pure research and practical implications in a way that is genuinely useful for anyone working in technology or business leadership. With a 4.9-star rating on Apple Podcasts, listeners clearly appreciate the approach. Episodes cover quantum money, self-destructing digital signatures, quantum networking, and the race to build quantum-resistant encryption standards. The biweekly schedule gives each episode breathing room, and the production is polished. If your interest in quantum computing leans toward "what does this mean for my organization" rather than "explain the physics to me," this is the show to prioritize. Karagiannis treats his audience like smart professionals who need actionable context, not a lecture.
