Two-dimensional quantum materials and devices for scalable integrated photonic circuits

ended

The proposed project aims at developing scalable quantum networks, based on photonic chip integration of novel 2D material quantum devices, with the main goal to demonstrate all-optical on-chip quantum processing. The recent demonstration of effortless integration of 2D materials onto photonics and CMOS platforms will result in a breakthrough in the development of on-chip quantum networks. 2D-SIPC will take full advantage of the huge variety of 2D materials and heterostructures and prototype novel quantum devices with revolutionary functionalities. In particular, we will develop electrically driven and entangled single photon emitters, broadband and high temperature single photon detectors, ultra-fast waveguide integrated optical modulators and non-linear gates. To pave the way to scalable networks, 2D-SIPC will develop large scale growth techniques of the most promising 2D materials. With this unique combination of features 2D-SIPC will allow the first demonstration of on-chip optical quantum processing, a key milestone for many quantum network concepts, such as extended secure quantum communication, scaling up of quantum computers and simulators, and novel quantum sensing applications with entangled photons. In particular, as these topics cover all four Quantum Technology pillars of the Quantum Flagship, our proposal makes a strong strategic link to each one of them. Beyond the 2D-SIPC platform, each developed component will be exploited in such distant fields as biological and medical imaging, radio-astronomy and environmental monitoring. The 2D-SIPC consortium includes four academic and one industrial partner with a high degree of complementarity that are at the forefronts of their fields, including single photon detection (ICFO), theory and fabrication of 2D materials and their heterostructures (UNIMAN), single photon emission (UCAM), chip based photonic circuits (CNIT) and commercial single photon detection, single photon emission and packaging (SQ).
