Query: Parity switching and decoherence by quasiparticles in single-junction
  transmons   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 $10^6$ 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.
