Project objective

Quantum engineering exploits core quantum abilities such as superposition and entanglement, promising transformative technologies. The most prominent example is the quantum computer, which could solve global challenges in energy, health, and logistics far beyond today’s computational reach. Photonics is a powerful platform for the quantum computer, offering low decoherence and natural connectivity for distributed systems. Notably, 3 of the 4 recent demonstrations of quantum advantage, from Canadian and Chinese groups, relied on photonics. Yet these achievements involved only a limited number of qubits. The present lack of scalability is a fundamental barrier preventing the realization of full-scale quantum computers and demands a new generation of researchers.PHOTONIQC builds on Europe’s leadership in integrated quantum photonics to address scalability. Our distributed photonic quantum computing platform uses qubits encoded by single photons, deterministic single-photon sources, dense high-transmission chips, record-efficiency detectors, and new quantum algorithms. Together, these technologies form a pathway toward scalable and practical quantum computers. Current doctoral programmes do not offer the interdisciplinary expertise or entrepreneurial mindset required to drive application-oriented breakthroughs. PHOTONIQC unites leading European academic and industrial partners to train 15 Doctoral Candidates across theoretical, experimental, and industrial aspects of quantum technology. The programme equips them to bridge academia and industry, fostering innovation and enabling the creation of spin-outs to bring new quantum technologies to market. By cultivating highly skilled researchers, PHOTONIQC ensures Europe remains at the forefront of global quantum technology, overcoming the scalability bottleneck and advancing toward real-world quantum computing.
