The Nanophotonics Theory & Signal Processing Group at DTU Fotonik, Department of Photonics Engineering at the Technical University of Denmark is seeking a candidate for a PhD position in the field of design and simulations of highly efficient solid-state sources of single indistinguishable photons. The position is funded by the Sapere Aude DFF Starting Grant “Linear Optics Quantum Information Technology (LOQIT)
Description
Solid-state sources of single photons are expected to play an important role in various quantum information applications, such as secure communications, quantum computation and metrology. These applications generally require near-unity efficiency and a high single-photon purity as well as indistinguishable photon emission. Furthermore, the ideal single-photon source (SPS) should be deterministic and not involve heralding or spontaneous downwards conversion. A potential platform for such a source is a quantum emitter, e.g. an InAs quantum dot, embedded in a semiconductor material. However, in a bulk material, the symmetry of the quantum dot leads to light emission in all directions, and additionally the emitted photons are subject to decoherence effects due to vibrations in the solid-state environment. A big challenge in realizing an efficient source is thus establishing control of the light emission.
