In part two of this episode, Paulina Gomez, Ryan Lafler, Doug Schremp, and Paola Osorio delve into Quantum Key Distribution (QKD) and Post-Quantum Cryptography (PQC) algorithms. They discuss the principles of QKD, its challenges, and industry progress, as well as the development of PQC algorithms to deliver quantum-resistant encryption solutions. They also explore future milestones and the solutions that are available today to safeguard critical data and mitigate the quantum computing threat to enable quantum-secure communications.
