Abstract
Recent achievements leading, amongst other things, to the observation of the two-photon 1S–2S transition in antihydrogen are reviewed. We summarise some of the technical advances that were necessary to facilitate this, and how these addressed the requirements posed by the underlying physical processes. Aspects of the latter have been elucidated by simulations aimed at describing as closely as possible the experimental situations, and we describe some recent insights from that work. We will close with a look to the future.
