Characterizing decoherence rates of a superconducting qubit by direct microwave scattering
Yong Lu, Andreas Bengtsson, Jonathan J. Burnett +8
We experimentally investigate a superconducting qubit coupled to the end of an open transmission line, in a regime where the qubit decay rates to the transmission line and to its o…
A semiclassical analysis of dark state transient dynamics in waveguide circuit QED
E. Wiegand, B. Rousseaux, G. Johansson
The interaction between superconducting qubits and one-dimensional microwave transmission lines has been studied experimentally and theoretically in the past two decades. In this w…
Cavity-free vacuum-Rabi splitting in circuit quantum acoustodynamics
Andreas Ask, Maria Ekström, Per Delsing +1
Artificial atoms coupled to surface acoustic waves (SAWs) have played a crucial role in the recent development of circuit quantum acoustodynamics (cQAD). In this paper, we have inv…
Observation of broadband entanglement in microwave radiation from a single time-varying boundary condition
B. H. Schneider, A. Bengtsson, I. M. Svensson +4
Entangled pairs of microwave photons are commonly produced in the narrow frequency band of a resonator, which represents a modified vacuum density of states. We use a broadband, se…
Correlated Cooper pair transport and microwave photon emission in the dynamical Coulomb blockade
Juha Leppäkangas, Mikael Fogelström, Michael Marthaler +1
We study theoretically electromagnetic radiation emitted by inelastic Cooper-pair tunneling. We consider a dc-voltage-biased superconducting transmission line terminated by a Josep…
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…
