Fraxonium: Fractional fluxon states for qudit encoding
Luca Chirolli, Valentina Brosco, Uri Vool +2
We propose a superconducting circuit hosting low-lying states, well separated from the rest of the spectrum, that naturally realizes a qudit system protected from leakage error…

Cuprate Twistronics for Quantum Hardware
Tommaso Confalone, Flavia Lo Sardo, Yejin Lee +12
Recent advances in the manipulation of complex oxide layers, particularly the fabrication of atomically thin cuprate superconducting films via molecular beam epitaxy, have revealed…
