title = "Simple quantum state tomography of single-photon entanglement",
abstract = "We extended a scheme that evaluates delocalized bipartite single-photon entanglement to multipartite entanglement that reconstructs a partial density matrix by preparing weak local oscillators, which is simpler and more loss-tolerant than the conventional scheme. We experimentally demonstrated the utility of our scheme by reconstructing the density matrix of several 3-mode W-states, after confirming the mode overlap between measured photons and local oscillator photons by Hong-Ou-Mandel interference.",
