The Qombs project aims to create a quantum simulator platform made of ultracold atoms in optical lattices. The quantum platform will allow to design and engineer a new generation of quantum cascade laser frequency combs. This unprecedented quantum simulation of semiconductor structures will endow the devices with brand new features, like nonclassical emission modes, entanglement among the modes of the comb and parametric generation of comb patterns far from the central emission frequency. In parallel, the quantum simulation will allow to improve present-day performances of quantum cascade lasers (QCLs) and quantum well structures for photon detection. Full quantum simulation will be followed by real manufacturing and state-of-the-art characterization. The consortium gathers Research Institutions that have a leading expertise in the physics of ultracold atoms, quantum optics and have first introduced and developed frequency comb synthesizers and quantum well structures during the last 20 years. Moreover, half of the ten partners of the Project are companies of different size that are already leading the QCL and frequency comb market.
