QuiX Quantum announced Carina, a photonic quantum computing platform designed for deployment in customer data centers.
Developed as part of the German Aerospace Center's Quantum Computing Initiative (DLR QCI), Carina brings together photon generation, multiplexing, cluster-state generation, real-time feed-forward control, and photonic assembly management into a single measurement-based quantum computing stack. The room-temperature platform is designed to integrate with classical high-performance computing (HPC), AI, and data center infrastructure. QuiX said the Carina core hardware platform has been delivered to DLR QCI, where it will enter system integration, commissioning, and validation.
Carina is based on measurement-based quantum computing rather than conventional gate-based architecture. Developers can program familiar gate-based quantum algorithms, which the software stack translates into measurement-based operations performed through adaptive measurements on entangled cluster states with real-time feed-forward. QuiX said the platform integrates the technologies required for universal photonic quantum computing, with demonstration of a universal gate set planned during the ongoing integration and validation phases with DLR QCI.
The announcement builds on a series of technologies QuiX has introduced over the past year, including its Feed Forward Control Unit, which converts single-photon detector signals into real-time control actions, and its Photonic Assembly Control Unit, which provides a standardized control layer for photonic chips and assemblies. Together with photon generation, multiplexing, and cluster-state generation, the company said those technologies form a complete photonic quantum computing stack designed for deployment outside the laboratory.
QuiX argues that practical quantum computing requires more than advances in qubit hardware. Some quantum computing platforms continue to depend on cryogenic infrastructure and highly specialized operating environments, creating challenges for deployment, maintenance, and integration with enterprise computing infrastructure. Carina is designed for rack-based deployment, compatibility with optical networking technologies, and interoperability with classical HPC and AI environments, enabling customers to begin building operational workflows before utility-scale quantum computers become available.
According to a QuiX Quantum white paper, the Carina system occupies about 88 units of rack space, integrating photonic processors, control electronics, multiplexers, lasers, and single-photon detectors, with a maximum power consumption of 9 kilowatts (kW). Developed under the DLR QCI’s Universal Photonic Quantum Computer project, the system is intended to demonstrate the core technologies required for universal measurement-based photonic quantum computing during the current integration and validation phase while providing a foundation for future fault-tolerant systems.
"Carina marks a major milestone for QuiX and the photonic quantum computing industry towards deploying utility-scale quantum systems at customer sites," QuiX Quantum CEO Stefan Hengesbach said in a statement. "The field has been split between systems that could be commercialized quickly but were not built for universal, fault-tolerant computing, and architectures with long-term scalability potential that remained difficult to deploy. Carina is bringing those two requirements together into a universal architecture for installation into real customer environments."
