Journal ArticleDOI
Observation of the dynamical Casimir effect in a superconducting circuit
Christopher Wilson,Göran Johansson,Arsalan Pourkabirian,Michael Roger Andre Simoen,J. R. Johansson,Tim Duty,Franco Nori,Per Delsing +7 more
TL;DR: The dynamical Casimir effect is observed in a superconducting circuit consisting of a coplanar transmission line with a tunable electrical length and two-mode squeezing in the emitted radiation is detected, which is a signature of the quantum character of the generation process.
Journal ArticleDOI
The radio-frequency single-electron transistor (RF-SET): A fast and ultrasensitive electrometer
Robert Schoelkopf,Robert Schoelkopf,Paula Wahlgren,Paula Wahlgren,A. A. Kozhevnikov,A. A. Kozhevnikov,Per Delsing,Per Delsing,Daniel E. Prober,Daniel E. Prober +9 more
TL;DR: A new type of electrometer is described that uses a single-electron transistor (SET) and that allows large operating speeds and extremely high charge sensitivity, and in some ways is the electrostatic "dual" of the well-known radio-frequency superconducting quantum interference device.
Journal ArticleDOI
Propagating phonons coupled to an artificial atom
Martin V. Gustafsson,Martin V. Gustafsson,Thomas Aref,Anton Frisk Kockum,Maria K. Ekström,Göran Johansson,Per Delsing +6 more
TL;DR: This work couple propagating phonons to an artificial atom in the quantum regime and reproduce findings from quantum optics, with sound taking over the role of light.
Journal ArticleDOI
Demonstration of a Single-Photon Router in the Microwave Regime
TL;DR: This work embedded an artificial atom, a superconducting transmon qubit, in an open transmission line and investigated the strong scattering of incident microwave photons, using two-tone spectroscopy to study scattering from excited states and electromagnetically induced transparency (EIT).
Journal ArticleDOI
Tuning the field in a microwave resonator faster than the photon lifetime
Martin Sandberg,Christopher Wilson,Fredrik Persson,Thilo Bauch,Göran Johansson,Vitaly Shumeiko,Tim Duty,Per Delsing +7 more
TL;DR: In this paper, a tunable superconducting transmission line resonator with high quality factors and a large tuning range (several hundred megahertz) has been proposed, which can change the frequency of a few-photon field on a time scale orders of magnitude faster than the photon lifetime of the resonator.
