Presently, advancements in data handling, accompanied by a reduction in size, pave the way for emerging technologies like nanophotonics to complement existing information transport methods. The necessity for efficient photon and electron transport persists, despite its practical challenges due to varying scales. Optical properties, dictated by the conventional diffraction limit of light (usually in the hundreds of nanometres), pose compatibility issues with the prevalent scale of current microelectronics, typically in the tens of nanometres. This study proposes two distinct approaches to address this challenge. The first involves a hybrid plasmonic nanosystem featuring strategically positioned dual types of light-emitting nanosources on a silver nanowire electromagnetic waveguide. The second approach centers on integrating a single photon source with a photonic structure, utilizing a glass optical waveguide within photonics integrated circuits. We will provide examples of applications for quantum communications and quantum metrology.
