Furthermore, we can use this generalized Hong-Ou-Mandel interferometer to characterize temporal distinguishability.to be published in the proceedings of Coherence and Quantum Optics 9Quantum PhysicsDemonstration of Temporal Distinguishability of Three and Four Photons with Asymmetric Beam Splittertext
