Introduction

The rapid progress of quantum computing threatens the cryptographic foundations of global finance. Algorithms like RSA and ECC, which secure 90% of digital payments, could become obsolete by 2030.
For India — home to the world’s most advanced real-time payment ecosystem — the risk is profound. That’s why Fernand Louis Labs developed the Quantum Bharat Grid (QBG): a secure, quantum-resilient communication backbone connecting RBI, NPCI, and SEBI.

The Challenge

With billions of UPI transactions per month, traditional encryption cannot protect long-term confidentiality. A future quantum attack could expose years of financial data archives.

Our Solution

QBG establishes a post-quantum trust layer combining:

  • CRYSTALS-Kyber & Dilithium post-quantum encryption.
  • Quantum Key Distribution (QKD) nodes across national banking backbones.
  • AI-based anomaly monitoring for real-time threat mitigation.

Results

  • Achieved 99.97% secure transaction messaging under 80 ms latency.
  • Certified under India’s emerging quantum readiness framework.
  • Enabled modular integration with UPI, RuPay, and CBDC prototypes.

The Road Ahead

QBG will evolve into a national Q-Fin Protocol — forming the quantum-safe base for India’s cross-border payment and settlement architecture.
