South Korea’s quantum technology ecosystem has rapidly matured from obscurity into a well-organized force. Backed by a clear national strategy and increasing investments, Korea is making its mark through cutting-edge research at top universities, substantial government support for quantum computing and communications, and active participation from industry giants and startups alike. The country’s balanced focus – on quantum computing platforms, quantum-safe communications (QKD and PQC), and quantum sensing – reflects a holistic understanding of the quantum revolution’s impact. Technical milestones like multi-qubit photonic chips, large-scale QKD deployment , and novel PQC algorithms showcase Korea’s growing R&D prowess. At the same time, initiatives such as dedicated quantum grad schools and the training of thousands of specialists ensure that human capital will not be a bottleneck. Significantly, South Korea has embedded quantum technology into its broader economic and security policies – treating it as a critical technology for the future, much like ...
