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…
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…
