Detecting ground state qubit self-excitations in circuit QED: slow quantum anti-Zeno effect
C. Sabín, J. León, J. J. García-Ripoll
In this work we study an ultrastrong coupled qubit-cavity system subjected to slow repeated measurements. We demonstrate that even under a few imperfect measurements it is possible…
Deep Strong Coupling Regime of the Jaynes-Cummings model
J. Casanova, G. Romero, I. Lizuain +2
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,…
Quantum simulation of the Klein paradox with trapped ions
R. Gerritsma, B. Lanyon, G. Kirchmair +7
We report on quantum simulations of relativistic scattering dynamics using trapped ions. The simulated state of a scattering particle is encoded in both the electronic and vibratio…
Mapping the spatial distribution of entanglement in optical lattices
Emilio Alba, Geza Toth, Juan Jose Garcia-Ripoll
We study the entangled states that can be generated using two species of atoms trapped in independently movable, two-dimensional optical lattices. We show that using two sets of me…
Klein tunneling and Dirac potentials in trapped ions
J. Casanova, J. J. Garcia-Ripoll, R. Gerritsma +2
We propose the quantum simulation of the Dirac equation with potentials, allowing the study of relativistic scaterring and the Klein tunneling. This quantum relativistic effect per…
