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…
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…
Quantum computation with hybrid parafermion-spin qubits
Denis V. Kurlov, Melina Luethi, Anatoliy I. Lotkov +3
We propose a universal set of single- and two-qubit quantum gates acting on a hybrid qubit formed by coupling a quantum dot spin qubit to a parafermion qubit with…
Adiabatic Transformations in Dissipative and Non-Hermitian Phase Transitions
Pavel Orlov, Georgy V. Shlyapnikov, Denis V. Kurlov
The quantum geometric tensor has established itself as a general framework for the analysis and detection of equilibrium phase transitions in isolated quantum systems. We propose a…
