Konstantinos Karagiannis is the director of quantum computing services at Protiviti. He helps companies get ready for quantum opportunities and threats, including quantum portfolio optimization using cardinality constraints and post-quantum cryptography agility assessments. In this VISION by Protiviti Interview, Karagiannis sat down with Joe Kornik, editor-in-chief of VISION by Protiviti, to discuss the news that China may have broken military-grade encryption. Karagiannis sets the record straight on what happened, what it could mean for the future of classified information, and what organizations should be doing to prepare for a post-quantum world.
