      abstract     = {As the energy relaxation time of superconducting qubits
                      steadily improves, nonequilibrium quasiparticle excitations
                      above the superconducting gap emerge as an increasingly
                      relevant limit for qubit coherence. We measure fluctuations
                      in the number of quasiparticle excitations by continuously
                      monitoring the spontaneous quantum jumps between the states
                      of a fluxonium qubit, in conditions where relaxation is
                      dominated by quasiparticle loss. Resolution on the scale of
                      a single quasiparticle is obtained by performing quantum
                      nondemolition projective measurements within a time interval
                      much shorter than T1, using a quantum-limited amplifier
                      (Josephson parametric converter). The quantum jump
                      statistics switches between the expected Poisson
                      distribution and a non-Poissonian one, indicating large
                      relative fluctuations in the quasiparticle population, on
                      time scales varying from seconds to hours. This dynamics can
                      be modified controllably by injecting quasiparticles or by
                      seeding quasiparticle-trapping vortices by cooling down in a
                      magnetic field.},
