      abstract     = {Superconducting circuits have attracted growing interest in
                      recent years as a promising candidate for fault-tolerant
                      quantum information processing. Extensive efforts have
                      always been taken to completely shield these circuits from
                      external magnetic fields to protect the integrity of the
                      superconductivity. Here we show vortices can improve the
                      performance of superconducting qubits by reducing the
                      lifetimes of detrimental single-electron-like excitations
                      known as quasiparticles. Using a contactless injection
                      technique with unprecedented dynamic range, we
                      quantitatively distinguish between recombination and
                      trapping mechanisms in controlling the dynamics of residual
                      quasiparticle, and show quantized changes in quasiparticle
                      trapping rate because of individual vortices. These results
                      highlight the prominent role of quasiparticle trapping in
                      future development of superconducting qubits, and provide a
                      powerful characterization tool along the way.},
