Signature of exceptional point phase transition in Hermitian systems
T. T. Sergeev, A. A. Zyablovsky, E. S. Andrianov +1
Exceptional point (EP) is a spectral singularity in non-Hermitian systems. The passing over the EP leads to a phase transition, which endows the system with unconventional features…
Radiation trapping effect versus superradiance in quantum simulation of light-matter interaction
S. V. Remizov, A. A. Zhukov, W. V. Pogosov +1
We propose a realization of two remarkable effects of Dicke physics in quantum simulation of light-matter many-body interactions with artificial quantum systems. These effects are…
Modeling dynamics of entangled physical systems with superconducting quantum computer
A. A. Zhukov, W. V. Pogosov, Yu. E. Lozovik
We implement several quantum algorithms in real five-qubit superconducting quantum processor IBMqx4 to perform quantum computation of the dynamics of spin-1/2 particles interacting…
Parametrically driven hybrid qubits-photon systems: dissipation-induced quantum entanglement and photon production from vacuum
S. V. Remizov, A. A. Zhukov, D. S. Shapiro +2
We consider a dissipative evolution of parametrically-driven qubits-cavity system under the periodical modulation of coupling energy between two subsystems, which leads to the ampl…
Dynamics of mesoscopic qubit ensemble coupled to cavity: role of collective dark states
A. A. Zhukov, D. S. Shapiro, W. V. Pogosov +1
We consider dynamics of a disordered ensemble of qubits interacting with single mode photon field, which is described by exactly solvable inhomogeneous Dicke model. In particular,…
Quantum entanglement for two qubits in a nonstationary cavity
Oleg L. Berman, Roman Ya. Kezerashvili, Yurii E. Lozovik
The quantum entanglement and the probability of the dynamical Lamb effect for two qubits caused by non-adiabatic fast change of the boundary conditions are studied. The conditional…
