Brief description: Quantum information could spur breakthroughs in quantum communication, quantum key distribution and quantum computation. Quantum emitters that can generate single photons and pairs of entangled photons on demand are key to the development of such technologies. Perovskite quantum dots (PQDs) hold great potential for use as quantum emitters, but the lack of stable two-photon photoluminescence signals and the low biexciton photoluminescence quantum yields limit their use. The QESPEM project will investigate nanoscale plasmon–exciton (plexciton) interactions. The presence of plexciton states could significantly stabilise and improve the photoluminescence properties of PQDs, rendering them suitable for producing single, pure photons.
