Quantum Cryptography Market to Reach $5.1 Billion by 2035

Quantum Cryptography Market is projected to grow from $502.2 million in 2025 to $5,123.8 million by 2035, expanding at a CAGR of 26.2% during the forecast period. The rapid increase in cyberattacks, rising deployment of quantum-safe communication infrastructure, and growing investments in next-generation encryption technologies are accelerating market demand globally. Governments and enterprises are increasingly adopting quantum cryptography solutions to secure financial transactions, defence communications, healthcare data, and cloud infrastructure from future quantum computing threats. A major macroeconomic driver for the market is the rising global investment in cybersecurity and digital infrastructure modernisation. According to the European Commission, the European Quantum Communication Infrastructure (EuroQCI) initiative involves all 27 EU member states and aims to build a secure quantum communication network integrating terrestrial fibre and satellite-based systems for protecting critical infrastructure and government communications. The initiative includes 19 cross-border infrastructure projects with total investments of nearly €193 million for quantum communication deployment and testing activities. The increasing integration of quantum-secure communication systems into national cybersecurity frameworks is creating strong commercial demand for quantum key distribution (QKD), quantum random number generation, and post-quantum cryptography solutions.

The hardware segment is expected to witness the fastest growth owing to the rising deployment of quantum communication devices, quantum key distribution systems, photonic processors, and quantum network infrastructure across government and enterprise applications. The expansion of critical infrastructure security projects, defence modernisation initiatives, and telecom network encryption programs is significantly increasing hardware adoption worldwide. According to the European Commission, EuroQCI deployment programs are integrating QKD-enabled fibre communication infrastructure across national and cross-border networks to safeguard sensitive data and strategic communications. Several strategic developments have further strengthened the market landscape. Key industry developments include:

• In November 2025, QNu Labs demonstrated India’s first and one of the world’s most extensive quantum key distribution (QKD) networks spanning over 500 km on existing optical fiber infrastructure, announced at ESTIC 2025 in the presence of India’s Union Minister, the Principal Scientific Adviser to the Prime Minister’s Office, and senior officials from DST and other agencies.

• In May 2025, Singapore telecom operator SPTel announced it had successfully trialed Southeast Asia’s first quantum-secure network, partnering with SpeQtral, Toshiba Digital Solutions, and ST Engineering to deploy Toshiba’s quantum key distribution (QKD) system and ST Engineering’s quantum-enabled encryptors over SPTel’s ultra-low latency fiber network as part of the National Quantum-Safe Network Plus (NQSN+) initiative.

Additionally, several telecom operators and cybersecurity vendors are collaborating with national governments to integrate post-quantum cryptography into cloud, financial, and defense communication systems to prepare for future quantum computing risks.
