The encryption protecting organizational data transmissions won't survive quantum computing maturity. Quantum computers will break RSA, Diffie-Hellman, and elliptic-curve cryptography securing today's networks and communications infrastructure. Adversaries are executing "harvest now, decrypt later" attacks—copying encrypted communications today for future decryption once quantum computing matures. The question isn't whether your encryption will fail, but whether you'll implement quantum-safe protection before that failure exposes decades of sensitive data.
The Quantum Threat to Network Infrastructure is Already Here
- Quantum computers will break current encryption foundations using mathematical vulnerabilities in RSA and elliptic-curve cryptography within 5-10 years
- Field-tested Differential Phase Shift QKD achieved 271 Kb/s secure key rates at 40 kilometers on standard telecommunications fiber infrastructure
- Quantum key distribution leverages physics to generate encryption keys—any eavesdropping attempt disturbs quantum states immediately revealing intrusion
- DPS-QKD protocol demonstrates superior performance against photon-number-splitting attacks with linear rather than quadratic distance degradation
- Commercial router integration validated following ETSI recommendations—enabling quantum protection without replacing functional network infrastructure
- Data requiring 5+ year protection—medical records, financial transactions, classified information, intellectual property—faces immediate quantum-enabled decryption risk
Global Organizations Are Deploying Quantum-Safe Networks
- Defense communications: Quantum-hardening classified information networks and command systems under national security mandates and sovereign control requirements
- Financial networks: Protecting transaction systems and interbank communications requiring decades-long confidentiality assurance and regulatory compliance
- Healthcare providers: Securing patient records and medical communications classified as critical infrastructure with permanent sensitivity requirements
- Enterprise communications: Safeguarding intellectual property and competitive intelligence for operational advantage and future-proof security posture
India's Indigenous Quantum Security Leadership
QNu Labs develops indigenous quantum technology providing organizations worldwide with alternatives to foreign security dependencies. Every system component—from quantum key distribution to quantum random number generators—originates from Indian innovation, tested under real field conditions. We've successfully deployed operational quantum security on standard fiber infrastructure with NIST-validated performance across defense, financial, healthcare, and enterprise sectors.
The Cost of Delay Compounds Daily
Every encrypted communication copied today becomes vulnerable data tomorrow. Standards bodies including ETSI and NIST are establishing quantum-safe frameworks because the threat timeline is measured in years, not decades. Organizations building security strategies today determine whether they'll lead their industries in post-quantum readiness or scramble after vulnerabilities materialize. Proactive quantum-safe deployment delivers strategic positioning through proven 271 Kb/s performance and commercial integration eliminating deployment barriers.
