What is the size of Quantum Cryptography Market?

According to 6Wresearch internal database and industry insights, the Global Quantum Cryptography Market was valued at USD 600 Billion in 2024 and is expected to reach USD 1400 Billion by 2031, growing at a compound annual growth rate of 11.70% during the forecast period (2025-2031).

The main drivers of this growth are the accelerating threat landscape for conventional encryption, organisations’ urgent need for quantum-safe communication infrastructure, and rising investment in quantum key distribution and quantum-random-number-generation technologies to secure critical data flows.

Growth Factors for Quantum Cryptography Industry

Surge in quantum computing development is raising concerns over breaking legacy encryption.
Heightened regulatory focus on data sovereignty and secure communications boosts deployment.
Financial services, defence and telecom sectors are prioritising quantum-secure infrastructures.
Hardware advancements and cost-reductions in quantum cryptography systems are enhancing accessibility.
Expansion of quantum-safe cloud and network solutions is enabling broader enterprise adoption.

Quantum Cryptography Market Trends

The Quantum Cryptography Market trends show increasing adoption of quantum-key-distribution (QKD) systems over fibre-optic and satellite links, and the deployment of quantum random number generators (QRNG) in cloud and enterprise environments. Enterprises are moving away from purely algorithm-based encryption toward physics-based security solutions. Moreover, managed quantum-security services and integration of quantum components into existing cybersecurity stacks are becoming more mainstream.

Emerging Developments in the Quantum Cryptography Market

The Quantum Cryptography Market developments include collaborations between quantum-communications providers and major telecom operators to deploy metro- and backbone-scale QKD networks. Vendors are introducing turnkey quantum cryptography appliance offerings, and “quantum-as-a-service” models are gaining interest for enterprises unable to deploy full on-premise systems. Standardisation efforts and satellite-based key-distribution pilots are further unlocking new deployment scenarios.
