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…
Dynamical entanglement percolation with spatially correlated disorder
Lorenzo Cirigliano, Valentina Brosco, Claudio Castellano +3
The distribution of entanglement between the nodes of a quantum network plays a fundamental role in quantum information applications. In this work, we investigate the dynamics of a…
Holonomic multi-controlled gates for single-photon states
Carlo Danieli, Valentina Brosco, Claudio Conti +1
Controlled and multi-controlled quantum gates, whose action on a target qubit depends on the state of multiple control qubits, represent a fundamental logical building block for co…
Optimal quantum key distribution networks: capacitance versus security
Lorenzo Cirigliano, Valentina Brosco, Claudio Castellano +2
The rate and security of quantum communications between users placed at arbitrary points of a quantum communication network depend on the structure of the network, on its extension…
