Arqit SKA-Platform vs QbitShield: Side-by-Side Comparison (2026)

Arqit SKA-Platform: Quantum-safe key agreement platform for securing comms across endpoints. built by Arqit. Core capabilities include Dynamic quantum-safe encryption key generation at endpoints via lightweight software agents, Over-the-Air (OTA) bootstrap key delivery using NIST ML-KEM post-quantum algorithms, Mutual authentication with per-session key rotation for perfect forward secrecy..

QbitShield: Quantum key distribution platform using prime-indexed phase rotations (PB-QKD). built by QbitShield. Core capabilities include Prime-Basis QKD (PB-QKD) via prime-indexed phase rotation state preparation, REST API for quantum key generation with configurable prime sequences and bases, Multi-basis QKD operation beyond standard BB84 with higher entropy..

Both serve the Quantum Security market but differ in approach, feature depth, and target audience.
