      abstract     = {Significant progress has been made in superconducting
                      quantum circuits. However new quantum devices that have
                      longer decoherence times at higher temperatures are urgently
                      required for quantum technologies. Superconducting nanowires
                      with quantum phase slips are promising candidates for use in
                      novel quantum devices. Here, we demonstrate YBa2Cu3O7-x
                      nanowires with phase-slip dynamics and study their
                      switching-current statistics at temperatures below 20 K.
                      We apply theoretical models developed for Josephson
                      junctions and show that our results provide strong evidence
                      for energy-level quantization in the nanowires. The
                      crossover temperature to the quantum regime of 12–13 K
                      and the lifetime in the excited state exceeding 20 ms at
                      5.4 K are superior to those in conventional Josephson
                      junctions. We also show how the absorption of a single
                      photon changes the phase-slip and quantum state of a
                      nanowire, which is important for the development of
                      single-photon detectors with high operating temperature and
                      superior temporal resolution.},
