Abstract

Scaling up quantum computers and building a quantum internet requires the development of ideal photon sources. Heralded single photon sources on integrated photonic platforms are the way forward to achieve this goal. Here we identify inconsistencies in source characterisation and propose methods to facilitate fairer comparison and better understanding of which sources could enable next-generation quantum applications.
