Quantum Interference of multiple on-chip heralded sources of pure single photons

Quantum Interference of multiple on-chip heralded sources of pure single photons
Quantum Interference of multiple on-chip heralded sources of pure single photons
We demonstrate the generation of heralded single photons in silica photonic chips with a preparation efficiency of 80% and single photon purity of 0.86. We show multiple indistinguishable photon sources on a single chip with HOM-dip visibilities of up to 95%.

Abstract

We demonstrate the generation of heralded single photons in silica photonic chips with a preparation efficiency of 80% and single photon purity of 0.86. We show multiple indistinguishable photon sources on a single chip with HOM-dip visibilities of up to 95%.
