Arqit SKA-Platform vs QiSpace™ SEQUR: 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..

QiSpace™ SEQUR: QEaaS platform for quantum entropy generation and secure distribution to endpoints. built by Quantropi. Core capabilities include Multisource quantum random number generation (QRNG) with entropy source diversity, Quantum-secure entropy distribution using Quantum Permutation Pad (QPP) technology achieving Shannon Perfect Secrecy, Gigabit-per-second entropy distribution over existing internet infrastructure..

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