On-chip integration of quantum electronics and photonics (ONCHIPS)

Discover the future of hexagonal SiGe research by connecting with experts, exchanging ideas, and exploring cutting-edge developments in its properties and applications at the 4th International Workshop on Hexagonal SiGe and Related Materials. The workshop takes place on 14 - 15 September 2026 at the University of Twente and is organized by the ONCHIPS project, focusing on both fundamental research and future technological directions.

The Horizon Europe project ONCHIPS aims to provide a unique silicon-based integrated architecture by developing key building blocks for quantum technologies.

Such a technology combines the best of two worlds: it would interface individual spin qubits and photons, and drastically enhance the scalability of quantum systems. The ONCHIPS’ novel silicon platform integrating quantum electronics and photonics will make a high impact in the quantum community and semiconductor industry positioning Europe at the forefront of these domains.

In a unique and interdisciplinary approach, ONCHIPS partners join their forces to address the major key challenges in realizing this technology interfacing individual spin qubits and photons.

By using a new CMOS compatible and optically active material system - direct bandgap GeSi which won the Physics World 2020Breakthrough - the ONCHIPS partners will realize for the first-time quantum heterostructures, spin qubits, electronic and photonic quantum devices and spin-photon interfaces with the ultimate goal to integrate the electronics and photonics in a single silicon-based system.
