Quantum technology leverages unique phenomena such as superposition, entanglement, and measurement effects to achieve capabilities that surpass classical physics, operating across three primary domains: quantum computing, quantum sensing, and quantum networking. This emerging field has garnered significant global investment, with annual expenditures exceeding tens of billions of dollars, as governments worldwide prioritize quantum capabilities for economic and national security reasons. The strategic importance of quantum technology is underscored by its potential to disrupt existing cryptographic systems, with recent developments in China accelerating the need for migration to post-quantum cryptography (PQC)1. As a result, the urgency to plan for PQC implementation has increased, making it essential for practitioners to stay informed about quantum technology advancements and their potential impact on cryptographic systems. This matters to cybersecurity professionals, as the impending shift to PQC will require significant updates to existing security protocols and infrastructure.
