QUPLAS (QUantum interferometry and gravitation with Positrons and LASers) is an experimental project for the study of antimatter; it makes use of positrons and positronium and mainly aims at performing quantum interferometry, decoherence and gravitational studies. The first phase of the project, called QUPLAS-0, consisted in the first successful demonstration of quantum interference of an antimatter particle: the positron. The experimental apparatus is composed by the positron beam, the interferometer, and the detector. This paper describes these three elements of QUPLAS-0 and how they were combined to achieve the goal of positron interference.
