WebSep 22, 2024 · The exchange phase θ grants a varying control over the photon pair degree of distinguishability. ( C) Two detection protocols: (I) UI D denotes the total photon counting signal (generating a 1/0 event registry), and (II) UII D denotes the frequency-resolved counting (generating frequency-dependent 1/0 list). M1, mirror 1; M2, mirror 2. WebFor realistic photon sources at the input of a linear multiport, photon distinguishability affects “quantumness” of such a device HOM ; Mult1 ; Ou ; Mult2 ; AHOM .For example, quantum supremacy of the Boson Sampling requires that indistinguishability of single photons must be very small NDBS ; TB .In general, the probability distribution at the output …

Webpartial photon distinguishability in GBS, except for a re-cent paper38 claiming to extend their results for partial distinguishability in AABS to that in GBS. The results of Ref.38 are somewhat unsatisfactory in the sense that their results for GBS must be applied in a context simi-lar to AABS. For example, their investigation is strictly 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 ... eaton proxy 2021
