                      performance of superconducting qubits by reducing their
                      coherence. We are investigating a source of quasiparticles
                      that has been too long neglected, namely radioactivity:
                      cosmic rays, environmental radioactivity and contaminants in
                      the materials can all generate phonons of energy sufficient
                      to break Cooper pairs and thus increase the number of
                      quasiparticles. In this contribution, we describe the status
                      of the project and its perspectives.},
