      abstract     = {The transmon superconducting qubit is being intensely
                      investigated as a promising approach for the physical
                      implementation of quantum information processing, and
                      high-quality factors of order 106 have been achieved both in
                      two- and three-dimensional architectures. These high-quality
                      factors enable detailed investigations of decoherence
                      mechanisms. An intrinsic decoherence process originates from
                      the coupling between the qubit degree of freedom and the
                      quasiparticles that tunnel across Josephson junctions. In a
                      transmon, tunneling of a single quasiparticle is associated
                      with a change in parity. Here we present the theory of the
                      parity-switching rates in single-junction transmons and
                      compare it with recent measurements. We also show that
                      parity switching can have an important role in limiting the
                      coherence time},
