Superconducting singlet-triplet qubits

Anatoliy Lotkov, Maria Spethmann, Daniel Loss

Hybrid devices integrating quantum dots with Josephson junctions are gaining interest because they combine spin-based quantum computing with circuit quantum electrodynamics (circui…

From coupled $Z_{3}$ Rabi models to the $Z_{3}$ Potts model

Anatoliy I. Lotkov, Valerii K. Kozin, Denis V. Kurlov +2

We study $Z_{3}$ -symmetric Rabi model that describes a three-level system coupled to two bosonic modes. We derive a mapping of the two-mode $Z_{3}$ Rabi model onto a…

Cat states in one- and two-mode $Z_{3}$ Rabi models

Anatoliy I. Lotkov, Denis V. Kurlov, Valerii K. Kozin +2

We investigate one- and two-mode variants of the $Z_{3}$ -symmetric quantum Rabi model, which describe the interaction of a qutrit with one or two bosonic modes and are direc…
