Photon distinguishability

WebJun 14, 2013 · In addition, we found the probability of two-photon distinguishability (which equals one minus visibility of two photon interference) to be p dist = 4.51 ± 0.11%. This probability of distinguishability takes into account all contributions that might deteriorate the visibility of two photon interference such as non-identical spectra and ... WebMar 20, 2024 · Our study uses simulations to investigate the effects of two-photon temporal distinguishability in terms of the visibility of the HOM-dip of two photons on the final key rate of finite-size MDI-QKD. Furthermore, an acceptable time delay range was estimated based on photons with Gaussian spectral amplitude functions.
