Yu-Shiba-Rusinov–Bond Qubit in a Double Quantum Dot with Circuit-QED Operation

Connecting two half-filled quantum dots to two superconducting leads induces a competition of bonds, with the dots forming either an interdot exchange bond or two individual Yu-Shiba-Rusinov (YSR) screening bonds with the leads. Defining a qubit using these singlet-parity bonding states provides dot...
