QuiX Quantum, a European developer of integrated photonic quantum computing hardware, has announced the commercial availability of Alquor 2.0, the next generation of its programmable, rack-mountable quantum photonic processor. Available in 8-mode, 20-mode and 32-mode configurations, the system is designed to reduce laboratory complexity and accelerate experimental progress across quantum optics, quantum communication, boson sampling, quantum information processing and photonic quantum computing research.

Photonic quantum experiments often depend on complex optical-table arrangements that must be manually configured, aligned and stabilized. Alquor 2.0 brings these capabilities into a programmable integrated platform, allowing research teams to spend less time maintaining experimental infrastructure and more time conducting and refining experiments. Its architecture also supports more reproducible workflows by allowing optical transformations to be programmed and repeated without rebuilding the physical arrangement for each experiment.

The QuiX Quantum Alquor 2.0 brings a programmable quantum photonic processor, control electronics and thermal management into a 3U rack-mountable system designed to reduce the complexity of optical-table experiments.

Built on QuiX Quantum’s silicon nitride photonic technology, Alquor 2.0 is integrated with the company’s Photonic Assembly Control Unit architecture. The system operates at room temperature as a fully programmable multimode linear optical interferometer, bringing the photonic processor, control electronics, thermal management and software interface together within a ruggedized 3U chassis designed for installation in a standard 19-inch equipment rack.

QuiX Quantum reports that more than 20 earlier Alquor systems have been deployed. Alquor 2.0 builds on that installed base with greater scalability, updated control electronics, improved thermal stability and configurations supporting 8-mode, 20-mode and 32-mode research environments.

“Photonic quantum research should not be limited by the complexity of repeatedly configuring, aligning, and stabilizing optical table setups,” said Caterina Taballione, Commercial & Partnership Lead at QuiX Quantum. “Alquor 2.0 gives researchers a programmable and reproducible platform, so they can spend less time managing experimental infrastructure and more time advancing quantum science.”

Current-driver-based control is intended to reduce electrical crosstalk between phase shifters, while air-cooled thermal management supports stable operation in modern laboratory, data center and high-performance computing environments. Ethernet connectivity and a Python interface allow researchers to incorporate the processor into automated experimental workflows and larger research infrastructures. Hot-swappable photonic assemblies include local calibration and characterization data, supporting replacement and reconfiguration workflows within the wider system. The PACU control architecture is designed to manage as many as 1,000 thermo-optic modulators and includes 32 high-speed RF connectors for external control systems and potential future fast-feed-forward capabilities. Those figures describe the capacity of the broader control architecture, while the currently available Alquor 2.0 processors support as many as 32 operational optical modes.

Research teams can use Alquor 2.0 for boson sampling, quantum random walks, quantum communication, quantum sensing, optical switching and the development of photonic quantum computing architectures. Its programmable optical interferometer allows researchers to configure different transformations on the same processor, supporting experimental comparison, faster iteration and reproducible results.

Earlier Alquor processors have been used by university and institutional teams investigating open quantum systems, molecular simulations, sampling algorithms, photon-source reliability and quantum-search methods. Research reported in 2025 used 12-mode and 20-mode integrated photonic processors to implement deterministic Grover search, producing an average success probability of 99.77%, with an uncertainty of plus or minus 0.05%, across the database sizes and marked elements evaluated. QuiX Quantum supplied the 20-mode processor used in that work. Separate research used a 12-mode silicon nitride processor associated with the QuiX platform to investigate boson sampling as a hardware accelerator for Monte Carlo integration. The supporting research referenced by QuiX Quantum includes both published work and arXiv preprints.

Alquor 2.0 is commercially available in 8-mode, 20-mode and 32-mode configurations. Final pricing depends on the selected configuration, delivery scope, service options and customer-specific requirements. Universities, research organizations and other customers can contact QuiX Quantum for configuration guidance, delivery schedules and tailored quotations.
