Quantum circuits with multiterminal Josephson-Andreev junctions
We explore superconducting quantum circuits where several leads are simultaneously
connected beyond the tunneling regime, such that the fermionic structure of Andreev bound …

Using bifluxon tunneling to protect the fluxonium qubit
Encoding quantum information in quantum states with disjoint wave-function support and
noise-insensitive energies is the key behind the idea of qubit protection. While fully …
