Phys.</i> <b>2005</b>, <i>7</i>, 219; Mooij et al. <i>Nat. Phys.</i> <b>2006</b>, <i>2</i>, 169; Khlebnikov http://arxiv.org/abs/quant-ph/0210019 2007]. It has also been theoretically predicted that the occurrence of QPS significantly changes the current-phase relationship (CPR) of the wire due to the tunneling between topologically different metastable states [Khlebnikov <i>Phys. Rev. B</i> <b>2008</b>, <i>78</i>, 014512]. We present studies on the microwave response of the superconducting nanowires to reveal their CPRs. First, we demonstrate a simple nanowire fabrication technique, based on commercially available adhesive tapes, which allows making thin superconducting wire from different metals. We compare the resistance vs temperature curves of Mo<sub>76</sub>Ge<sub>24</sub> and Al nanowires to the classical and quantum models of phase slips. In order to describe the experimentally observed microwave responses of these nanowires, we use the McCumber−Stewart model [McCumber <i>J. Appl. Phys.</i> <b>1968</b>, <i>39</i>, 3113; Stewart <i>Appl. Phys. Lett.</i> <b>1968</b>, <i>12</i>, 277], which is generalized to include either classical or quantum CPR. 2009-05-13 00:00:00 microwave responses superconducting nanowires QPS superconducting wire quantum CPR nanowire fabrication technique resistance vs temperature curves New J Appl phase slips microwave response quantum bit metastable states Adhesive TapeQuantum phase slippage Superconducting Nanowires Al nanowires Khlebnikov Phys Quantum Phase Slips quantum models McCumber J al superconducting nanowire Mo 76Ge Mooij
