Key Takeaways
• QKD Market forecast to reach USD XX Billion by 2030, registering 25-28% CAGR.
• Increasing adoption across defense, banking, telecom, healthcare, and government sectors.
• QKD emerging as a core pillar of quantum-safe cryptography for long-term data protection.
• Governments launching national quantum communication networks & satellite-based QKD projects.
• High growth in entanglement-based QKD, CV-QKD, DV-QKD, and integrated photonic QKD systems.

Market Story: Why QKD Is Becoming Essential for Future-Proof Cybersecurity
As quantum computing advances, traditional encryption algorithms such as RSA and ECC face the risk of being cracked within minutes. Global enterprises and national agencies are now preparing for a "harvest now, decrypt later" cyber threat scenario, where attackers store encrypted data today to decrypt it when quantum hardware matures.

Quantum Key Distribution eliminates this risk by enabling:
• Unbreakable encryption keys based on quantum physics
• Instant detection of eavesdropping attempts
• Secure transmission for critical infrastructure
• Long-term protection for confidential data
QKD is rapidly being integrated into telecom fiber networks, satellite communication links, cross-border financial systems, and government defense networks.
Countries including the U.S., China, India, the UK, Germany, Japan, and South Korea are investing billions into quantum-secure communication infrastructure.
