We investigate the interaction of two two-level qubits with a single mode quantum field in a cavity without rotating wave approximation and considering that qubits can be located at an arbitrary distance from each other. We demonstrate that there exists a radiation induced interaction potential between atoms. We studied the properties of the system numerically and in addition constructed a simple analytical approximation. It is shown that the observable characteristics are substantially…

Two-Qubit Local Fisher Information Correlation beyond Entanglement in a Nonlinear Generalized Cavity with an Intrinsic Decoherence
TLDR
It is shown that the robustness, against decoherence, of the generated two-qubit correlations can be controlled by qubit–qubit coupling and the initial coherent cavity states.
Dynamics of entanglement and population inversion of two qubits in a hybrid nonlinear system
An analytical solution is obtained when the Kerr medium and Stark shift are considered as nonlinear interaction terms to the system containing two-qubit and two-mode electromagnetic field from the ...

Entanglement between qubits induced by a common environment with a gap
We study a system of two qubits interacting with a common environment, described by a two-spin boson model. We demonstrate two competing roles of the environment: inducing entanglement between the
Resolution of gauge ambiguities in ultrastrong-coupling cavity quantum electrodynamics
In quantum electrodynamics, the choice of gauge influences the form of light–matter interactions. However, gauge invariance implies that all physical results should be independent of this formal
Variational generalized rotating-wave approximation in the two-qubit quantum Rabi model
We present an analytical method for the two-qubit quantum Rabi model. While still operating in the frame of the generalized rotating-wave approximation (GRWA), our method further embraces the idea of
Tavis-Cummings model beyond the rotating wave approximation: Quasidegenerate qubits
The Tavis-Cummings model for more than one qubit interacting with a common oscillator mode is extended beyond the rotating wave approximation (RWA). We explore the parameter regime in which the
Manipulating quantum entanglement with atoms and photons in a cavity
After they have interacted, quantum particles generally behave as a single nonseparable entangled system. The concept of entanglement plays an essential role in quantum physics. We have performed
Spontaneous emission in a quantum system driven by the resonant field beyond the rotating wave approximation
Quasi-stationary states of the quantum system in the driving resonant field are considered without rotating wave approximation. Conditions under which the spontaneous emission could be suppressed in
Multiphoton Jaynes-Cummings Model: Arbitrary Rotations in Fock Space and Quantum Filters.
TLDR
The multiphoton Jaynes-Cummings model is investigated and applications in quantum information science are explored and a Fock state filter, or quantum scissor, is implemented that restricts the dynamics of a given bosonic mode to a limited Hilbert space.
Ultrastrong coupling between light and matter
Light–matter coupling with strength comparable to the bare transition frequencies of the system is called ultrastrong. This Review surveys how experiments have realized ultrastrong coupling in the
Cavity quantum electrodynamics
This paper reviews the work on cavity quantum electrodynamics of free atoms. In recent years, cavity experiments have also been conducted on a variety of solid-state systems resulting in many
