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 Rabi models to the Potts model
Anatoliy I. Lotkov, Valerii K. Kozin, Denis V. Kurlov +2
We study -symmetric Rabi model that describes a three-level system coupled to two bosonic modes. We derive a mapping of the two-mode Rabi model onto a…
Robust Tripartite Entanglement Generation via Correlated Noise in Spin Qubits
Sander Driessen, Ji Zou, Even Thingstad +2
We investigate the generation of genuine tripartite entanglement in a triangular spin-qubit system due to spatially correlated noise. In particular, we demonstrate how the formatio…
Heisenberg-limited metrology from the quantum-quench dynamics of an anisotropic ferromagnet
Z. M. McIntyre, Ji Zou, Jelena Klinovaja +1
The emerging field of quantum magnonics seeks to understand and harness the quantum properties of magnons -- quantized collective spin excitations in magnets. Squeezed magnon state…
Cat states in one- and two-mode Rabi models
Anatoliy I. Lotkov, Denis V. Kurlov, Valerii K. Kozin +2
We investigate one- and two-mode variants of the -symmetric quantum Rabi model, which describe the interaction of a qutrit with one or two bosonic modes and are direc…
