Indonesia’s Digital Insights into Quantum Security Technology

Quantum computing promises transformative advances in optimisation, data-intensive research, and scientific discovery, yet it simultaneously threatens the foundations of classical cryptography that protect global digital infrastructures. This conceptual study examines Indonesia’s readiness for quantum security by analysing literature, global best practices, and policy frameworks. The study highlights the urgency of transitioning to post-quantum cryptography (PQC), adopting quantum key distribution (QKD), and strengthening national governance capacities to mitigate risks such as the “store now, decrypt later†threat. Findings reveal that Indonesia’s growing digital dependence in government services, e-commerce, and financial technology magnifies exposure to future quantum breaches. National readiness requires integrated policies, capacity building, and regional cooperation to align with emerging international standards. Quantum security is shown not merely as a defensive response but as a strategic enabler of resilience, innovation, and competitiveness. Early action will position Indonesia to safeguard its digital sovereignty and contribute to global quantum-safe ecosystems.
