Abstract

Nano emitters either natural or artificial are nano objects able to emit non classical light such as single or entangled photons They are a potential resource for a growing host of applications in quantum technologies and quantum information sciences A particular growing interest is in effectively harvesting light from quantum emitters operating at room temperature such as nanocrystals quantum dots color centers in diamond or defect states in two dimensional materials An efficient high quality and bright photon source yet still simple compact and cheap could be achieved with such room temperature emitters in principle Yet very efficient photon harvesting could be quite tricky as room temperature emitters usually have broad spectral and spatial emission profiles and they are in many cases substrate free and hard to integrate and with inherent low emission rates and poor directionality In this talk I will review our efforts to overcome the inherent problems of room temperature nano emitters and in particular of nanocrystal quantum dots as useful photon sources by designing hybrid nano emitter nano antenna devices that can efficiently extract and direct single or two photon states towards the goal of producing high purity bright deterministic and heralded single photon sources on chip
