The photon, being chargeless and massless, is the ideal qubit material since it is the only elementary particle with no decoherence. Based on over 25 years of research at the Center for Nanoscience and Nanotechnology (C2N, CNRS and Univ. of Paris Saclay), we demonstrated the world's first efficient emission of single photons powered by our unique semiconductor-based technology (Nature Photonics, 2016). In just a few years, we completed the design and construction of PROMETHEUS which integrates all the necessary components to deterministically generate qubits based on single photons. PROMETHEUS is the main building block for MOSAIQ, our full-stack photonic quantum computing platform, integrating all the building blocks from PROMETHEUS, to the photonic chips, efficient detectors and all the software stack, including open-source PERCEVAL, to control and simulate hardware and algorithm layer. MOSAIQ is designed and built to be modular, reconfigurable, interconnected and therefore scalable.
