University of Twente aims to scale photonic quantum computing
The main goal of the QU-PIC project is to develop a toolkit of PIC-based building blocks to support rapid progress from a concept to a fully packaged system
The University of Twente is coordinating a novel project aimed at accelerating the development of quantum computing systems. Entitled QU-PIC, the initiative aims to establish European leadership in the emerging field of quantum technology, with a toolbox of quantum building blocks based on integrated photonics.
Quantum computers, with their potential to perform calculations beyond the reach of classical supercomputers, are at the forefront of scientific innovation. Photonics is one of the main enabling technologies for quantum computing systems. But, since these systems are usually based on bulk optics – where huge tables filled with lasers are needed to manipulate and read out ions – they are not yet scalable. QU-PIC therefore wants to make quantum computing systems smaller and more stable and scalable.
The researchers and companies collaborating believe there is a need for a universal photonic integrated platform that can operate with light from the UV to mid-infrared parts of the spectrum – a broader range of light than is currently possible. “The integrated photonics platforms studied so far do not cover the UV, leading to complicated integration schemes where several passive PIC platforms need to be combined,” explains Sonia Garcia Blanco, project lead and professor in the Integrated Optical Systems group at the University of Twente.
QU-PIC's overarching goal is to create a toolkit of PIC-based quantum building blocks that facilitates the swift progression from conceptualisation to a fully packaged quantum computing system. By developing essential technologies within the European supply chain, the initiative also seeks to contribute significantly to establishing European leadership in the emerging quantum field.
The QU-PIC project is being conducted by an international consortium of 11 research institutes and companies. As well as the University of Twente, participating organisations include Ghent University, Quix Quantum, Tematys, TOPTICA Photonic, Aluvia Photonics, WWU Münster, Technische Universität Berlin, Chalmers University of Technology, Physikalisch-Technische Bundesanstalt, and Eagleyard Photonics.
