Replication Data for: YBa2Cu3O7 as a high-temperature superinductor

The magnetic behavior of type-II superconductors is explained by a quantum vortex with a supercurrent encircling a coherence-length sized core. In a superconducting film with thickness t < λL, the vortex field decays slowly as 1/r2, extending to the Pearl length 𝑃𝐿=2𝜆𝐿2𝑡, known as the Pearl vortex, rather than diverging as log(1/r) and decaying with London penetration depth, λL, as in Abrikosov vortex. However, the effect of Pearl vortex on large enhancement of kinetic inductance had not been fully explored. Here, we discovered Pearl inductance, an additional form of kinetic inductance arising from geometrical structuring of high-Tc YBCO superconductor thin films (Tc~81K) at the 𝑃𝐿 scale. This results from extension of vortex screening supercurrents from λL to 14λL in an ultrathin meta-atom of thickness λL/7, enabling terahertz superinductance. Our device show impedance exceeding the quantum resistance limit 𝑅𝑄≈6.47 𝑘Ω by 33%, offering possibilities for cutting-edge electronic, photonic, and quantum devices.
