Probing the quantum vacuum with an artificial atom in front of a mirror
I. -C. Hoi, A. F. Kockum, L. Tornberg +4
Quantum fluctuations of the vacuum are both a surprising and fundamental phenomenon of nature. Understood as virtual photons flitting in and out of existence, they still have a ver…
Storage and on-demand release of microwaves using superconducting resonators with tunable coupling
Mathieu Pierre, Ida-Maria Svensson, Sankar Raman Sathyamoorthy +2
We present a system which allows to tune the coupling between a superconducting resonator and a transmission line. This storage resonator is addressed through a second, coupling re…
Designing frequency-dependent relaxation rates and Lamb shift for a giant artificial atom
Anton Frisk Kockum, Per Delsing, Göran Johansson
In traditional quantum optics, where the interaction between atoms and light at optical frequencies is studied, the atoms can be approximated as point-like when compared to the wav…
Propagating phonons coupled to an artificial atom
Martin V. Gustafsson, Thomas Aref, Anton Frisk Kockum +3
Quantum information can be stored in micromechanical resonators, encoded as quanta of vibration known as phonons. The vibrational motion is then restricted to the stationary eigenm…
Dynamical Casimir effect entangles artificial atoms
S. Felicetti, M. Sanz, L. Lamata +4
We show that the physics underlying the dynamical Casimir effect may generate multipartite quantum correlations. To achieve it, we propose a circuit quantum electrodynamics (cQED)…
Twin paradox with macroscopic clocks in superconducting circuits
Joel Lindkvist, Carlos Sabín, Ivette Fuentes +4
We propose an implementation of a twin paradox scenario in superconducting circuits, with velocities as large as a few percent of the speed of light. Ultrafast modulation of the bo…
