摘要

Abstract

Entanglement plays a vital role in quantum information processing. Owing to its unique material properties

silicon carbide recently emerged as a promising candidate for the scalable implementation of advanced quantum information processing capabilities. To date

however

only entanglement of nuclear spins has been reported in silicon carbide

while an entangled photon source

whether it is based on bulk or chip-scale technologies

has remained elusive. Here

we report the demonstration of an entangled photon source in an integrated silicon carbide platform for the first time. Specifically

strongly correlated photon pairs are efficiently generated at the telecom C-band wavelength through implementing spontaneous four-wave mixing in a compact microring resonator in the 4H-silicon-carbide-on-insulator platform. The maximum coincidence-to-accidental ratio exceeds 600 at a pump power of 0.17 mW

corre

sponding to a pair generation rate of (9 ± 1) × 10

pairs/s. Energy-time entanglement is created and verified for such signal-idler photon pairs

with the two-photon interference fringes exhibiting a visibility larger than 99%. The heralded single-photon properties are also measured

with the heralded

demonstrating the SiC platform as a prospective fully integrated

complementary metal-oxide-semiconductor compatible single-photon source for quantum applications.
