Abstract

During the past decade, quantum optics development has been showing an interesting platform option for experimental implementation of quantum information and fundamental quantum mechanic tests. Implementation using single photons, using heralded or entangled source, have versatility to be manipulated on free space, fiber optics or photonic chips. This project proposes to study sources of correlated photons in photonic chips to miniaturize experimental implementations using quantum optics. The chip design can be done using a similar design of free space experimental setup or can be used designs only possible in wave-guide. The photonic chips are based on silicon nitride wave-guide, allowing the generation and manipulation of correlated photons in the visible and near infrared light. This band of the electromagnetic spectrum allows the integration of different quantum computation platforms, such as: ion traps and alkaline atoms. (AU)
