Towards phonon routing: Controlling propagating acoustic waves in the quantum regime
M K Ekström, T Aref, A Ask +5
We explore routing of propagating phonons in analogy with previous experiments on photons. Surface acoustic waves (SAWs) in the microwave regime are scattered by a superconducting…

Nonexponential decay of a giant artificial atom
Gustav Andersson, Baladitya Suri, Lingzhen Guo +2
In quantum optics, light-matter interaction has conventionally been studied using small atoms interacting with electromagnetic fields with wavelength several orders of magnitude la…

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…
