The composition of dark matter is one of the puzzling topics in astrophysics. Since, the existence of axions would fill this gap of knowledge, several experiments for the search of axions have been designed in the last twenty years. Among all the others, light shining through walls experiments promise to push the exclusion limits to lower energies. To this end, effort is put for the development of single-photon detectors operating at frequencies <100 Ghz. Here, we review recent advancements in

In particular, we present two sensors based on one-dimensional Josephson junctions with the capability to be in situ tuned by simple current bias: the nanoscale transition edge sensor (nano-TES) and the Josephson escape sensor (JES). These two sensors seem to be the perfect candidates for the realization of microwave light shining through walls (LSW) experiments, since they show unprecedented frequency resolutions of about 100 GHz and 2 GHz for the nano-TES and JES, respectively.
