Quantum technologies and photonic integration are envisaged to solve the current limitations of the information technology and completely change the paradigms of computing and. However, this expected revolution still mostly based on theoretical concepts, which have not yet been implemented as applications. One of the major obstacles in integrated photonics being the lack of unified platform which would provide all functionalities required for integrated quantum information processing.

QuantSi aims for the development of scalable and fully integrated Si-based photonic platform providing single photon generation, detection, and manipulation on a single chip by combining epitaxial III-V semiconductor quantum dots, superconducting nanowire single photon detectors with the existing Si technology. QauntSi combines state-of-the-art molecular beam epitaxy, nanofabrication, and advanced techniques of experimental optics in an interdisciplinary and international research environment.
