Konstantinos Karagiannis, who leads quantum computing services at Protiviti, joins Yuval Boger to discuss the dual aspects of quantum computing: its promise in transformative use cases and its threats in post-quantum cryptography. Konstantinos explains why organizations need to act now to secure their data against future quantum threats, emphasizing the importance of cryptographic agility and hybrid solutions. He highlights how different industries, particularly financial services and government, are leading the way in adopting post-quantum standards. They also explore the challenges of quantum key distribution, the evolving vendor landscape, and how organizations can prioritize their post-quantum journeys.
