“…Since the early 1990s, various apparatus for two-photon interference experiments have been utilized to investigate two-photon wavepacket interference phenomena, e.g., the Mach-Zehnder interferometer (MZI) 2 17 19 21 23 24 and the Michelson interferometer (MI) 25 26 27 . The majority of the experiments involving these devices were performed using two identical photons as the input state, where the two photons simultaneously entered the input port of an interferometer.…”

We present experimental demonstrations of two-photon interference involving temporally separated photons within two types of interferometers: a Mach-Zehnder interferometer and a polarization-based Michelson interferometer. The two-photon states are probabilistically prepared in a symmetrically superposed state within the two interferometer arms by introducing a large time delay between two input photons; this state is composed of two temporally separated photons, which are in two different or the same spatial modes. We then observe two-photon interference fringes involving both the Hong-Ou-Mandel interference effect and the interference of path-entangled two-photon states simultaneously in a single interferometric setup. The observed two-photon interference fringes provide simultaneous observation of the interferometric properties of the single-photon and two-photon wavepackets. The observations can also facilitate a more comprehensive understanding of the origins of the interference phenomena arising from spatially bunched/anti-bunched two-photon states comprised of two temporally separated photons within the interferometer arms.

“…(31), Eq. (33) admits τ 1 = τ 2 = τ 3 = τ 4 = 0 as unique solution, hence proving that for k = 4 we can have the exclusive zero-coincidence point condition (2). Firstly, let us observe that we can exclude the cases with τ 2 = τ 4 = 0.…”

A generalized multi-parameter Hong-Ou-Mandel interferometer is presented which extends the conventional "Mandel dip" configuration to the case where a symmetric biphoton source is used to monitor the contemporary presence of k independent time-delays. Our construction results in a two-input/two-output setup, obtained by concatenating 50:50 beam splitters with a collection of adjustable achromatic wave-plates. For k = 1, 2 and k = 4 explicit examples can be exhibited that prove the possibility of uniquely linking the zero value of the coincidence counts registered at the output of the interferometer, with the contemporary absence of all the time-delays. Interestingly enough the same result cannot be extended to k = 3. Besides, the sensitivity of the interferometer is analyzed when the time-delays are affected by the fluctuations over time-scales that are larger than the inverse of the frequency of the pump used to generate the biphoton state. PACS numbers: 42.50.-p, 03.67.-a arXiv:1907.12270v1 [quant-ph] 29 Jul 2019ters. This manuscript finally ends with Sec. V where we present our conclusions and comments on the possible applications to sensing procedures.

“…The second term corresponds to the interference of two identical monochromatic modes. This term is equivalent to the Hong-Ou-Mandel (HOM) effect [17,25]. The third term accounts for the interference of two photons going through different arms [cases iii and iv in Fig.…”

“…In the collinear geometry, downconverted photon pairs become spatially indistinguishable. Galvez et al and Odate et al have recently measured collinear fourth-order interference [24,25], but these studies did not consider the spectral properties of the pump photons. Furthermore, the measurements have been performed for restricted path-length differences.…”

The interference of entangled photon pairs permits the study of the fundamental properties of quantum mechanics. The process is also finding practical applications in optical imaging. The Michelson interferometer provides an elegant means for characterizing the degree of two-photon entanglement, but the technique has not yet been described and analyzed in detail. Here we provide a full description of the interference of collinear down-converted photons in a Michelson interferometer. We explain the basic elements that characterize the interference pattern and complement the theory with experimental measurements. The two-photon Michelson interferometer can be used in quantum optical coherence tomography for dispersion-free imaging and localization.
