摘要

在第二次量子革命的背景下,操纵量子系统的能力已被用于各种技术和越来越多的技术示范,其中大部分是低能量光子。在此框架下,我们打算将量子技术扩展到伽马光子。我们的目标是利用与高能粒子,特别是电子-正电子湮灭量子的纠缠所带来的资源。低频量子实验的工具不适合穿透辐射,因此我们需要使用典型的 keV-MeV 能量范围的效应。高能光子协议将包括基本特性测试、工业成像、量子随机数发生器、量子模拟器、军事应用以及改进现有的医疗程序。在本文中,我们回顾了湮灭光子相关性研究的一些重要步骤,指出了量子光子实验中能量增加方面的实验差异和必要性,并介绍了我们为证明基于伽马射线协议的可行性实验而提出的量子伽马设备的设计方案。我们的项目旨在证明通过纠缠量子在对低能量光子不透明的介质中进行通信的可能性。

Towards quantum technologies with gamma photons

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.
