Fully on-chip photonic turnkey quantum source for entangled qubit/qudit state generation Photonics

Posted by in categories: computing, quantum physics

An electrically driven on-chip light source of entangled photon pairs is developed by combining an InP gain section and Si3N4 microrings. A pair generation rate of 8,200 counts s−1 and a coincidence-to-accidental ratio of more than 80 are achieved around the wavelength of 1,550 nm.
