ABSTRACT |
Single photons and entangled photons lie at the heart of photonic quantum technologies, whose performances are optimal when the purity of the single or entangled photons is high. However, the multiphoton emission, dissipation, and decoherence in practical realizations can easily lead to the degradation of the single- and entangled- photon quality. The purification of single or entangled photons is thus valuable to restore the performance of quantum technologies. Recently, we demonstrated the single- and entangled- photon purification by temporally shaping the quantum wavepackets. As two examples, I will talk about how we purify the polarization-entangled photons from spontaneous parametric down-conversion as well as the single photons from the colloidal quantum dots. |
