Quantum Cryptography Market by Solution (Quantum Key Distribution (QKD), Quantum Random Number Generators (QRNG), Quantum-safe Cryptography), Service (Deployment & Integration, Crypto Consulting) - Global Forecast to 2031

The global quantum cryptography market size is projected to grow from USD 1.6 billion in 2025 to USD 10.2 billion by 2031 at a Compound Annual Growth Rate (CAGR) of 35.7% during the forecast period.

The move toward software-defined quantum security is creating strong market momentum as enterprises and telecom operators integrate quantum-secure key management, QKD routing, and PQC controls into SDN and automated network orchestration platforms. This enables programmable quantum-security layers, dynamic key refresh, automated policy enforcement, and seamless integration of quantum-safe communication across multi-cloud, metro, and backbone networks. As networks become increasingly virtualized and distributed, the demand for software-driven, quantum-safe control planes continues to accelerate.

By organization size, the large enterprises segment accounts for the largest market share.

Large enterprises represent the largest market share in quantum cryptography because they manage vast communication networks, handle sensitive multi-regional operations, and must secure long-term data across distributed infrastructures. Industries such as global banking, cloud service providers, utilities, and aerospace rely on quantum-safe channels to protect cross-site traffic and high-value intellectual property. In 2024, a major European telecom operator completed a pilot using QKD to secure traffic between two core network sites, demonstrating how large organizations are integrating quantum-secure links into existing optical infrastructure. Large enterprises also lead adoption due to stringent internal security frameworks, dedicated cybersecurity teams, and the need to safeguard mission-critical systems from future quantum decryption threats, making them the primary drivers of real-world deployment.

By offering, the services segment is expected to account for the highest growth rate during the forecast period.

Cloud deployment is growing at the fastest rate as enterprises shift workloads to multi-cloud and hybrid environments, requiring quantum-safe protection for data-in-motion, APIs, and distributed applications. Cloud service providers are integrating PQC-ready key management, quantum-safe TLS, and QRNG-backed entropy services directly into their security stacks, allowing organizations to adopt quantum protection without deploying specialized hardware. In 2024, several global cloud vendors began testing PQC-enabled VPN gateways and quantum-secure inter-region links to support regulated industries. This momentum is driven by ease of scalability, rapid deployment, and the ability to extend quantum-safe communication across geographically dispersed environments, making cloud-based quantum security a preferred path for enterprises to modernize their infrastructure.

By region, North America is estimated to account for the largest market size.

The Asia Pacific quantum cryptography market is expanding rapidly due to strong government investment, national quantum-communication programs, and early commercial deployments. China continues to advance its large-scale QKD networks, including its multi-city quantum backbone and satellite-based quantum links, which were launched in recent years. Japan has been developing metro-level QKD testbeds with telecom operators since 2023, focusing on secure financial transactions and data-center interconnects. South Korea has integrated QKD into parts of its national telecom infrastructure and expanded pilot projects for 5G backhaul security in 2024. India also strengthened the market through its National Quantum Mission, announced in April 2023, which allocated approximately USD 726 million to accelerate QKD research, secure communication trials, and quantum network development. Across the region, strong public funding, technology partnerships, and telecom-driven deployments are accelerating real-world adoption of quantum-secure communication.
