qtlabs - Quantum Technology Laboratories GmbH Tech Stack

Quantum key distribution systems and satellite-based secure communication

Aviation and Aerospace Component Manufacturing Vienna, Wien 11–50 employees Founded 2017 Privately Held

qtlabs builds quantum cryptography prototypes and ground infrastructure for space-based secure communication. The stack is embedded-systems focused (FPGA, ASIC, C/C++, RTOS), reflecting deep hardware and protocol work rather than software-as-a-service—a profile that matches their active projects around satellite optical payloads, ground station development, and link characterization. Pain points cluster around compliance, procurement, and design assurance, suggesting they operate in regulated aerospace/defense channels where correctness and traceability dominate over velocity.
