QbitShield vs SECQAI TPM: Side-by-Side Comparison (2026)

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..

SECQAI TPM: Post-quantum TPM hardware for server, edge, and custom PCB deployments. built by SECQAI. Core capabilities include Post-Quantum Cryptography acceleration via lattice-based hardware accelerators, Post-quantum firmware signing for embedded software, Continuous device attestation from factory to production..

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