All-fiber three-path Mach-Zehnder interferometer
TLDR
This three-path Mach-Zehnder interferometer has an analog in two-photon interferometry, and is believed to be the first nontrivial example of N x N multiport interferometers.Abstract:
We report the realization of a three-path Mach-Zehnder interferometer using single-mode fibers and two integrated 3 x 3 fiber couplers. We observed enhanced phase sensitivity, as compared with two-path interferometers, with a visibility of the interference pattern of more than 97%. This interferometer has an analog in two-photon interferometry, and we believe it to be the first nontrivial example of N x N multiport interferometers.read more

A scheme for efficient quantum computation with linear optics.
TL;DR: It is shown that efficient quantum computation is possible using only beam splitters, phase shifters, single photon sources and photo-detectors and are robust against errors from photon loss and detector inefficiency.

TL;DR: In this article, the authors reviewed the original theory and its improvements, and a few examples of experimental two-qubit gates are given, and the use of realistic components, the errors they induce in the computation, and how these errors can be corrected is discussed.

TL;DR: A review of the progress in photonic quantum information processing can be found in this article, where the emphasis is given to the creation of photonic entanglement of various forms, tests of the completeness of quantum mechanics (in particular, violations of local realism), quantum information protocols for quantum communication, and quantum computation with linear optics.

Realizable higher-dimensional two-particle entanglements via multiport beam splitters
TL;DR: In this article, it was shown that one is by no means constrained to entangled spin systems, and to Stern-Gerlach apparatuses, and the concept of generalized Bell numbers was employed, which is more suitable than the standard set of spin eigenvalues.
