Purification of Heralded Single Photons by Conditional Pumping
Yung-Cheng Kao, Chin-Sung Chuu · Quantum 2.0 Conference and Exhibition · 2024
We experimentally demonstrated a novel approach to purify the heralded single photons from parametric down conversion. By implementing a conditional pumping scheme, we observed the reduction of g2(0) without scarifying the generation rates.
