LIGENTEC joins Swiss Quantum Hub

We are delighted to announce that LIGENTEC SA, leader in low loss Silicon Nitride Integrated Photonics, has become a member of the Swiss Quantum Hub (SQH). Swiss based LIGENTEC provides custom specific integrated photonics circuits for a wide range of applications such as LiDAR, Biosensing, Space and Quantum and is a spin-off from the EPFL Lausanne.

Geneva, May 2021

Recently, LIGENTEC was involved in a work which attracted a lot of attention in the photonic quantum computing area. By providing chips based on silicon nitride waveguides and thermo-optic phase shifters to Canadian based hardware company Xanadu Quantum Technologies Inc. – a SQH member – they allowed them to develop a programmable photonic quantum chip able to execute multiple algorithms at room-temperature. This work was published in the journal Nature.

“The SQH is proud to welcome LIGENTEC as a new member”, said Julien Levallois, President of the SQH. “LIGENTEC has a strong track record in the field of Photonic Integrated Circuits (PICs). The performance of their devices and service makes them the world leader in silicon nitride PICs and their recent successful collaboration with Xanadu is proof of this. No doubt this is only the beginning, and we look forward to working with them and to help them to expand their support of the quantum technologies industry.”

”Being able to contribute to this exciting and fast moving field of quantum technologies fills us with pride. We are convinced that integrated photonics technologies will play a key role in future quantum computing and quantum communication systems to support our society in generating a safe and sustainable future”, states co-founder Michael Geiselmann. “The Swiss Quantum Hub is a perfect platform to network and exchange along the value chain of this new vertical market with huge potential.”
