The quantum computing has reached a critical turning point as hardware developers move away from experimental laboratory setups and toward industrial-scale deployment. The Dutch photonics business MicroAlign has announced that it has received €2.5 million (about $3 million USD) in funding from the European Innovation Council (EIC) Accelerator, marking a significant milestone for the European deep-tech industry.
The goal of this strategic capital infusion is to expedite the industrialization of ultra-high-precision fiber array technology. It consists of an accelerator grant and a possible equity investment component. It is now acknowledged that these elements serve as a fundamental “building block” for the upcoming generation of photonic quantum computers.

Solving the “Hidden Bottleneck” of Quantum Hardware
“Hidden” supply chain obstacles are starting to appear as the quantum technology industry moves from pure research to early commercial use. Advanced photonic packaging is one of the most important of these. Photonic quantum systems, in contrast to conventional electrical computers, encode and transport quantum information using photons, which are light particles. Photons must be precisely steered into and out of quantum processors for these systems to function.
The link between integrated photonic circuits and optical fibers is a huge engineering problem brought on by this demand. Connecting photonic chips to external optical systems is mostly accomplished by fiber arrays, which contain many optical fibers in carefully designed arrangements. However, there is very little room for error. Significant photon losses can result from misalignments at these connecting points, even at the nanoscale scale. These losses do more than merely diminish a signal in the sensitive realm of quantum mechanics; they also impair computing accuracy and qubit coherence, which prevents dependable quantum operations.

Beyond Traditional Telecommunications Standards
The fact that traditional alignment solutions, which were first created for the data communications and telecommunications industries, are no longer adequate is one of the main problems the industry is currently experiencing. The passive assembly used in these conventional techniques frequently lacks the positional precision needed for quantum-scale processes. Even a small signal loss in a quantum system can have a detrimental effect on the computation’s overall fidelity.
MicroAlign, a 2021 spin-out from Eindhoven University of Technology, uses a proprietary micro-manipulation technology to solve this problem. MicroAlign‘s method achieves active, nanometer-scale alignment of individual optical fibers by using micro-actuators instead of static components. The integrity of a quantum states depends on ultra-low-loss optical coupling between fiber arrays and photonic chips, which is made possible by this active technique.
The Roadmap to 2026: Miniaturization and High-Density Interconnects
MicroAlign is striving to significantly reduce the size of its alignment platform as part of its ambitious technical strategy for the 2026 product cycle. Delivering a new generation of high-accuracy fiber arrays with channel pitches as small as 127 μm is the aim.
It is anticipated that this density breakthrough would revolutionize hardware design. Manufacturers of quantum computing will be able to include a lot more optical channels into smaller, chip-scale devices by decreasing the distance between channels. It is anticipated that this development would result in significant gains in system performance, efficiency, and scalability. The industry now considers reaching optical-coupling loss targets below 0.5 dB across multi-channel interfaces to be a fundamental necessity for high-performance systems rather than a luxury.

Industrialising the Supply Chain for High-Volume Production
Although a customized research setting can achieve precise alignment, the EIC grant is especially intended to advance this technology into high-volume production. Large-scale implementation of photonic quantum computers is anticipated to require thousands of fiber arrays. MicroAlign plans to use the EIC Accelerator cash to automate a large percentage of their production workflow to meet this expected demand.
To guarantee that the supply of essential components stays up with the schedules of hardware developers who are scaling their systems over the coming years, the company plans to transition from pilot-scale to automated high-volume manufacture. The need for dependable and expandable hardware supply chains is growing as the industry shifts to fault-tolerant systems.
A Strategic Asset for the Global Ecosystem
MicroAlign’s invention has ramifications that go well beyond the field of quantum computing. Several other high-end photonic domains are starting to demand precise fiber-to-chip integration, such as:
- MEMS optical switching systems
- Wavelength-selective switching technologies
- Optical amplification platforms
Performance in these domains depends on the capacity to reduce signal loss across multi-channel interfaces. Furthermore, with an emphasis on enhancing fiber-to-chip coupling for dispersed quantum nodes, MicroAlign has already played a significant part in cooperative European quantum innovation activities.

Looking Toward 2029 and Beyond
MicroAlign has set lofty long-term objectives with the help of the EIC Accelerator award. The company plans to supply the optical connectivity infrastructure for a sizeable chunk of the worldwide photonic quantum market by 2029.
There could be repercussions in a number of scientific and industrial domains if MicroAlign is successful in becoming the main supplier of this infrastructure. Advances in sophisticated materials research, artificial intelligence, and pharmaceutical medication development are anticipated to be fueled by increased quantum processing capacity. Furthermore, new opportunities in integrated optical systems, sensing technologies, and telecommunications may be made possible by the industrialization of scalable photonic packaging.
The EIC’s investment reflects a growing consensus in the deep-tech community that the development of dependable, scalable, and industrialized hardware supply chains that can support real-world deployment is more important for the “quantum age” than theoretical advances or qubit design. Technologies like precision fiber alignment are becoming more widely acknowledged as critical assets in the global technological landscape as the industry continues its shift from experimental platforms to deployable infrastructure.
