Linear Optics Quantum Information Technology


Welcome to the homepage for the single-photon source (SPS) activities at DTU Fotonik. Our objective is to develop high-efficiency photonic nanowire, micropillar and photonic crystal membrane-based SPSs for quantum cryptography and for quantum information processing.

The LOQIT project aims at establishing the physical understanding necessary to engineer sources of single indistinguishable photons and as well as entangled photon pairs with near-unity effiency approaching 100 %.

The project is funded by a Sapere Aude grant (ID: DFF – 4005-00370) awarded by the Danish Research Council for Technology and Production.
