Webcally that photon quantum states are not perfectly indistinguishable. The partial photon distinguishability presents a serious limitation in implementation of optical quantum … Webdistinguishability of photons is a fundamental and critical requirement. Any distinguishability will reduce the visibility of interference and the fidelity of quantum …
WebDec 11, 2006 · From this model, we find that the temporal (in)distinguishability of photons is related to the exchange symmetry of the multiphoton wave function. We find that simple … WebThis method requires quantification of distinguishability and photon purity parameters. The photon state purity is estimated using the calculated Joint Spectral Amplitude as shown in figure 2 , taking account of the non-ideal placement of the spectral filters, from which we estimate a single source purity of 0.97.
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. WebUnder these conditions, two identically polarized photons will always exhibit HOM interference; however, non-idealities in the photon sources or beam splitter characteristics …
