  • The coherence time describes the timescale over which particles can still display wave-like interference and is important for quantum optics. Using multi-photon interference experiments, Ra et al. show that the multi-photon coherence time depends on both the number of photons and the detection scheme used.

  • Photoelectron quantum-state tomography is demonstrated in helium and argon atoms upon the absorption of ultrashort, extreme ultraviolet light pulses. The purity and degree of entanglement of a mixed photoelectron and ion state are quantified following coherent two-photon ionization using an extreme ultraviolet pulse and two infrared pulses.

  • An experimental protocol to discern true multi-particle interference is demonstrated in a boson sampling device without dynamic reconfiguration. Statistical features of three-photon interference were evaluated in a seven-mode integrated interferometer.
