Periodic Reporting for period 1 - ONCHIPS (On-chip integration of quantum electronics and photonics)
Reporting period: 2022-10-01 to 2024-03-31
(1) We will for the first time grow advanced hex-GeSi heterostructures for quantum technology applications. (2) We will realise spin qubits in quantum dots in hex-GeSi. (3) We will create spin-photon interfaces in hex-GeSi, made possible by the direct bandgap of the material. (4) We will build single-photon detectors for wavelengths beyond 2 micrometers, optimized for emission from hex-GeSi.
This project will foster the integration of electronic and optoelectronic functionalities based on a silicon-based direct-bandgap semiconductor, using a combination of facilities and expertise that is available only in Europe. Hence ONCHIPS will establish a strong contribution to European innovation leadership in electronics, photonics, emerging enabling technologies in general, and quantum technologies in particular, making our contributions highly relevant for the work program. This new material has the potential to be compatible with standard silicon-based semiconductor technology, benefitting from established roadmaps on miniaturization and scalability.
ONCHIPS consortium partners collaborate with industry and end-users and identified key results with patent potential including the development of growth processes of SiGe nanowires (CNRS-Saclay and TU Eindhoven) and the development of single photon emitters (TU Munich and TU Eindhoven). The long wavelength (2–4 μm) superconducting nanowires single photon detectors developed by Single Quantum have two main potential markets: biomedical imaging and quantum communication. A potential business model is considered, the partners, interacting companies and adopters have been identified and a preliminary market evaluation and a stakeholder analysis have been performed.
