In the context of the second quantum revolution, the ability to manipulate quantum systems is already used for various techniques and a growing number of technology demonstrators, mostly with low energy photons. In this frame, our intention is to extend quantum technologies to gamma photons. Our aim is to take advantage of resources brought by entanglement with higher energy particles, particularly electron-positron annihilation quanta. Tools for low frequency quantum experiments are not suitable for penetrant radiation, consequently we need to use effects typical to the keV-MeV energy range instead. High energy photon protocols would include fundamental properties testing, industrial imaging, quantum random number generators, quantum simulators, military applications and improvement of already existing medical procedures. In this paper we review some important steps in the study of annihilation photon correlations, we point out the experimental differences and necessities with respect to the energy increase in quantum photonic experiments and we describe the design of a quantum gamma device we propose for experiments meant to prove feasibility of gamma ray based protocols. The perspective behind our project is to evidence the possibility to communicate via entangled quanta through media which are not transparent for low energy photons.

This work is meant to evidence the possibility of studying isotopic patterns of various environmental samples by means of gamma-ray spectrometry following neutron irradiation with a small intensity source. Patterns have a natural component due to the natural radioactive series and an artificial one, obtained following neutron irradiation. The goal is to evidence a low cost, rapid and accurate method and show main corrections and optimizations needed to improve actual and future results that allow material tracking in some cases, including in-situ gamma spectrometry under water.
