Deep strong coupling regime of the Jaynes-Cummings model.
We study the quantum dynamics of a two-level system interacting with a quantized harmonic oscillator in the deep strong coupling regime (DSC) of the Jaynes-Cummings model, that is, when the couplingExpand

Shortcut to adiabatic passage in two- and three-level atoms.
We propose a method to speed up adiabatic passage techniques in two-level and three-level atoms extending to the short-time domain their robustness with respect to parameter variations. ItExpand

Quantum Rabi Model with Trapped Ions
We propose the quantum simulation of the quantum Rabi model in all parameter regimes by means of detuned bichromatic sideband excitations of a single trapped ion. We show that current setups canExpand

Zeno physics in ultrastrong-coupling circuit QED
We study the Zeno and anti-Zeno effects in a superconducting qubit interacting strongly and ultrastrongly with a microwave resonator. Using a model of a frequently measured two-level systemExpand

Motional frequency shifts of trapped ions in the Lamb-Dicke regime
First order Doppler effects are usually ignored in laser driven trapped ions when the recoil frequency is much smaller than the trapping frequency (Lamb-Dicke regime). This means that the central,Expand

Transitionless quantum drivings for the harmonic oscillator
Two methods to change a quantum harmonic oscillator frequency without transitions in a finite time are described and compared. The first method, a transitionless-tracking algorithm, makes use of aExpand

Femtosecond laser ablation for microfluidics
We present some applications of femtosecond laser ablation for microfluidics. A doubled Ti:sapphire femtosecond laser (=400 nm; pulse width, 90 fs; pulse energy up to 350 µJ; pulse repetition rate, 1Expand

Energy consumption for Shortcuts To Adiabaticity
Shortcuts to adiabaticity let a system reach the results of a slow adiabatic process in a shorter time. We propose to quantify the "energy cost" of the shortcut by the energy consumption of theExpand

Circuit Quantum Electrodynamics with a Superconducting Quantum Point Contact
We consider a superconducting quantum point contact in a circuit quantum electrodynamics setup. We study three different configurations, attainable with current technology, where a quantum pointExpand

Generalized relation between pulsed and continuous measurements in the quantum Zeno effect
A relation is found between pulsed measurements of the excited-state probability of a two-level atom illuminated by a driving laser and a continuous measurement by a second laser coupling the excitedExpand
