Quantum solitons and their quantum walks in transmon arrays
Ben Blain, Giampiero Marchegiani, Luigi Amico +1
Superconducting qubits are artificial atoms whose spectra and interactions can be engineered through appropriate circuit design, a versatility that can be exploited for quantum sim…

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…
