Quantropi QiSpace SEQUR is a Quantum Entropy as a Service (QEaaS) platform that generates and distributes quantum entropy (true random numbers) to endpoints over existing network infrastructure. Core Functionality: - Generates quantum entropy using a multisource portfolio of quantum random number generators (QRNGs), providing entropy source diversity - Distributes quantum entropy securely to endpoints over standard internet infrastructure - Supports air-gapped deployments and customer-hosted middle-tier architectures for entropy sovereignty Entropy Generation: - Sources entropy from multiple physical quantum devices - Devices undergo continuous maintenance, monitoring, and randomness testing using multiple test suites - Customers receive auditable entropy quality reports Quantum-Secure Distribution: - Uses Quantropi's Quantum Permutation Pad (QPP) technology to encrypt transmissions - QPP achieves Shannon Perfect Secrecy via symmetric encryption - Distribution operates at gigabit-per-second speeds over existing internet infrastructure Entropy Sovereignty: - Customers retain full ownership and control over entropy generation, storage, and usage - Supports regional service selection based on customer requirements - Customers may supply their own entropy sources - Customer-hosted middle tier acts as a security boundary; Quantropi cannot access or reproduce customer entropy Entropy Expansion: - Uses QPP's high-entropy properties to expand short random seeds into long random number streams - Provides platform resiliency against peak demand - Supports connection-limited and offline endpoints Benchmarks: - Benchmarked by Deutsche Telekom in their OPENQKD lab - SEQUR SynQK variant supports the ETSI-014 QKD protocol standard - Outperformed photonic QKD distribution rates by over 250x in benchmarks
