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: A new quantum interferometric scheme based on three-dimensional waveguide devices based on Fock states is proposed and theoretically investigated, expected to open new perspectives to quantum enhanced sensing and metrology performed in integrated photonics.

TL;DR: In this article, the authors proposed a quantum information circuit for quantum joining, in which two qubits of information encoded in the polarization of two photons are re-encoded into the polarization and path degrees of freedom of a single photon, while keeping the overall quantum information constant.

TL;DR: In this paper, a new quantum interferometric scheme based on three-dimensional waveguide devices is proposed and theoretically investigated, which can be implemented by femtosecond laser waveguide writing, recently adopted for quantum applications.

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).
