Quantum computing continues to evolve rapidly, with photonic technology emerging as one of the most promising approaches for building scalable quantum systems. Unlike traditional quantum architectures that rely on superconducting circuits or trapped ions, photonic quantum systems use light particles to perform quantum operations, offering advantages in speed, stability and energy efficiency.
At the core of QuiX Quantum’s technology are its Photonic Assemblies (PAs), which contain the Photonic Integrated Circuits (PICs). These chips consist of complex matrices of optical channels and Thermal Optic Phase Shifters (TOPS), enabling precise control of light for quantum operations.
To support and control these assemblies, QuiX Quantum worked together with Dekimo Goes on the development of the Photonics Assembly Control Unit (PACU), a compact rack-mounted control unit designed to control and regulate the Photonic Assemblies.
Dekimo developed the PACU system enclosure including its internal main board and modular driver architecture. The main board supports up to 25 driver modules, with each module capable of controlling 40 independent current channels. This results in a scalable platform supporting up to 1000 independently controlled optical elements.
A technical challenge in the project was the thermal management of the photonic assembly. The PIC must operate at a constant temperature to ensure stable performance. This required the PACU to actively regulate both heating and cooling and efficiently transfer excess heat away from the PIC. One of the main design goals was to achieve this without water cooling, using only ventilation inside the system.
This development marks an important step in making quantum technology more scalable and practical for real-world applications, including future integration in high-performance computing environments.
