Nicolò Spagnolo,Chiara Vitelli,Chiara Vitelli,Lorenzo Aparo,Paolo Mataloni,Fabio Sciarrino,Andrea Crespi,Andrea Crespi,Roberta Ramponi,Roberta Ramponi,Roberto Osellame,Roberto Osellame +11 more
TL;DR: The experimental observation of three-photon interference in an integrated three-port directional coupler realized by ultrafast laser writing is reported, which allows for bosonic coalescence of three photons and opens new important perspectives in many areas of quantum information.

TL;DR: In this article, a quantum state fusion (QSFS) is defined as the physical process by which the internal quantum state of two particles (e.g., photons) is transferred into the four-dimensional internal quantum states of a single particle (photon) (Fig. 1).

TL;DR: In this paper, a three-port beam splitter was realized and tested in the quantum regime, which allowed us to observe bosonic coalescence of three photons, which is a purely quantum phenomenon deriving from the interference of two photons.
