Silicon Waveguide-based Single Photon Source with 12.4% High Off-chip Measured Heralding Efficiency

2023

We designed and fabricated a silicon chip-based heralded single-photon source with 12.4% off-chip measured heralding efficiency. In addition, we achieve a coincidence-to-accidental ratio of 443.7 and heralded self-correlation function of 0.0037 measured at a pair …

Entanglement distribution over 155 km metropolitan fiber using a CMOS-compatible silicon chip

2025 · Newton

Transmitting entangled states over long distances is crucial for developing quantum networks. Previous demonstrations using satellites or fibers relied on photon pairs generated from bulk crystal arrangements. Polarization entanglement distribution based on complementary metal-oxide-semiconductor (CMOS)-compatible …
