This report analyses deployment models for quantum-safe data transport (QSDT) between 2025 and 2035, based on the Harvest Now, Decrypt Later (HNDL) risk and standardisation/regulation dynamics. It compares the two technological pillars (PQC as the default and scalable route, QKD as a targeted complement for a limited number of ultra-critical links), describes the hybrid architecture and its operational impacts (protocols, performance, integration), maps the value chain (regulators, operators, equipment manufacturers, quantum suppliers, cloud), and then offers a market analysis (willingness to pay logic, sizing/forecast) and actionable recommendations for decision-makers and technical teams.
- Why is quantum-safe data transport becoming non-optional now?
- Which deployment model is most realistic at scale?
- Which use cases and sectors will adopt first, and how should data criticality and data lifetime drive prioritisation?
- How can organisations industrialise migration without breaking production systems?
- Who captures value across the ecosystem, and what are the dominant monetisation logics and willingness-to-pay drivers for quantum-safe transport?
- World
