Finland Allocates €6.9 Million ($8 Million USD) to Launch QScale Consortium for Optical Quantum Control and Cryogenic Packaging A multi-institutional Finnish research consortium has been awarded funding under Business Finland’s Rise to the Challenge program to launch the QScale project (“Scaling up quantum computing by telecom-based technologies”). Backed by a total budget of €6.9 million ($8 million USD)—including a €5.5 million ($6.4 million USD) primary grant from Business Finland—the three-year structural initiative aims to replace traditional electrical control cabling in superconducting quantum computers with high-speed, energy-efficient optical telecommunications infrastructure. Set to launch on September 1, 2026, the project is coordinated by the VTT Technical Research Centre of Finland in partnership with Tampere University and Aalto University, establishing a cross-disciplinary platform to bypass the thermal and energy bottlenecks that limit large-scale quantum processing arrays. Technical Architecture: Suppressing Cryogenic Thermal Load via Optical Signal Modulations The QScale initiative targets the thermal and electronic scaling boundaries encountered when managing superconducting quantum processing units (QPUs) beyond the thousand-qubit threshold. Contemporary gate-model superconducting systems rely on individual coaxial electrical cables routed from room-temperature control racks down into dilution refrigerators operating at milli-Kelvin temperatures (<20 mK). This electrical wiring setup conducts parasitic ambient heat into the ultra-cold environment, causing thermal noise that degrades qubit coherence times. As physical qubit arrays scale toward the million-qubit mark required for fault-tolerant operations, the cumulative thermal load from standard electrical infrastructure would increase energy consumption exponentially, potentially requiring an aggregate power input equivalent to the output of a nuclear reactor. To eliminate this thermal bottleneck, QScale is developing a light-based data transmission layer that interfaces directly with superconducting circuits. The technical roadmap replaces heavy coaxial lines with high-bandwidth, low-thermal-conductivity optical fibers to deliver control data into the cryogenic environment. This optical control framework operates via a multi-tiered component stack: High-Frequency Microwave Generation: Developing specialized on-chip optoelectronic components that convert modulated infrared laser pulses directly into ultra-precise, noise-free microwave control signals at cryogenic temperatures to manipulate qubit states.
Cryogenic Quantum Packaging: Engineering compact, low-temperature System-in-Package (SiP) modules that combine silicon photonics, high-frequency radiofrequency (RF) electronics, and superconducting circuits into a unified sub-assembly.
Integrated Piloting Facilities: Utilizing Tampere University’s SiPFAB (System-in-Package Fabrication) pilot line and the SoC Hub (System-on-Chip) to test micro- and nanofabricated optoelectronic modules under deep cryogenic conditions. Ecosystem Integration & Phase 1 Funding Distribution The initial phase of the QScale project will run from September 1, 2026, through August 31, 2029, focusing on foundational chip-level R&D and baseline hardware validation. Under the consortium’s capital structure, Tampere University will manage approximately €1.6 million ($1.8 million USD) of the total budget to lead RF signal generation and advanced packaging workflows under the direction of Associate Professor Jukka Viheriälä. The project will leverage Finland’s national research infrastructures, including the Finnish University Worldwide Radio Infrastructure (FUWIRI) and the Photonics Research and Innovation platform (FinnLight). The technology roadmap is designed to transition into a commercialization phase during the 2030s, targeting integration with high-performance computing (HPC) nodes to link quantum accelerators directly with classical supercomputing clusters. Pending successful progress metrics at the close of Phase 1, Business Finland’s framework permits a two-year extension phase starting in September 2029 to onboard commercial Finnish industry partners, scaling the optical control platform into an export-oriented technology stack for global quantum foundry installations.
