Today, most superconducting microwave resonators are made of ordinary, straight wires. A conventional single-wire resonator has an impedance bounded by the impedance of free space (377 \u03a9). In contrast, the resonators that we are developing reach impedances in the order of 104<\/sup>\u00a0\u03a9 by harnessing the mutual-inductance between concentric loops in a spiral pattern. Eventually, such low-loss superinductors can be used for new qubit designs that are robust against noise and for hybrid quantum architectures coupling superonducting circuits to spin qubits.<\/p>\n
