Europe Pushes Quantum Readiness With Photonic Chips
Europe is moving faster to prepare for practical quantum technologies. A new €50 million pilot project will play a central role in that effort.
From 2026, the Photonics for Quantum project, known as P4Q, will bring together experts from across Europe. Its goal is simple but critical. Turn fragile lab-scale photonic chips into reliable components that can be produced at scale.
Turning Research Into Manufacturable Technology
Quantum systems rely heavily on light. Photons carry information, enable precise sensing, and support secure communication.
However, many photonic chips still work only in controlled lab settings. They often fail when conditions change or when produced in larger numbers.
P4Q tackles this problem directly. It focuses on consistency, standard processes, and real-world performance. Instead of proving a device works once, the project aims to make sure it works every time.
As a result, Europe can move from research success to industrial production.
Why Photonic Chips Matter for Quantum Systems
Reliable photonic chips unlock progress across many fields.
In sensing, they can detect tiny traces of pollution in water. They can also help medical labs measure extremely weak biological signals.
In quantum computing, these chips help control and read quantum states. They are essential for scaling up future systems.
In communications, photonic chips support quantum secure networks. These networks protect data using the laws of physics, not software alone.
To meet these needs, P4Q is improving key features. These include lower optical losses, stable performance at very low temperatures, and smooth integration into larger systems.
A Shared European Manufacturing Ecosystem
One of P4Q’s strengths lies in its structure. The project brings together 29 partners from 12 European countries.
These partners include universities, research centres, start-ups, foundries, and large industrial firms. Together, they cover the full value chain.
A major focus is on shared design tools. Process Design Kits and Assembly Design Kits allow teams to work from common standards. This reduces errors and speeds up development.
The project supports several photonic platforms, such as silicon nitride, lithium niobate, and alumina. This gives developers flexibility based on their needs.
Lowering Barriers for Start-ups and SMEs
P4Q also expands access to testing and production facilities. Shared infrastructure allows smaller firms to use advanced manufacturing without high upfront costs.
As a result, innovation is not limited to large players. Startups can move faster from design to production.
This approach strengthens the entire European ecosystem.
Funding, Timeline, and Readiness Goals
The total investment in P4Q is €50 million. European funding and national contributions each cover half.
The project is organised into eight work packages. It aims to reach Technology Readiness Level 8 and Manufacturing Readiness Level 8.
In practical terms, this means the technology will be ready for large-scale demonstrations and industrial use.
Securing Europe’s Quantum Future
By focusing on dependable and scalable photonic chips, P4Q builds a solid base for future quantum systems.
As global competition grows, Europe needs more than strong research. It needs manufacturing strength.
Through coordination, shared tools, and targeted investment, P4Q positions photonic chips as a core part of Europe’s future digital infrastructure.
