Quantum Platform Architecture

Banking On Quantum establishes a vendor-agnostic, cryptographically agile framework that integrates hybrid classical-quantum computing into existing banking cores.

Core Architectural Layers

1. Cryptographic Agility & Key Management

• NIST Post-Quantum Standards: Native support for ML-KEM (Kyber) for key encapsulation, ML-DSA (Dilithium) for digital signatures, and SLH-DSA (SPHINCS+) for stateless hash-based signing.
• Hybrid TLS & Dual-Certificates: Concurrent validation of classical RSA/ECDSA and post-quantum keys ensuring zero downtime during multi-year institutional migration.

2. Quantum Algorithm Acceleration Engine

• Quantum Amplitude Estimation (QAE): Quadratic speedups for Value-at-Risk (VaR) and Expected Shortfall (ES) calculations.
• QAOA & VQE Solvers: Optimal collateral allocation, cash-sweep optimization, and trade-clearing batch schedules.

3. Hardware-Agnostic Abstraction Layer

• QPU Interoperability: Seamless execution across superconducting qubits, trapped-ion processors, photonic quantum hardware, and classical quantum simulators.
