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…
Surface acoustic wave unidirectional transducers for quantum applications
Maria K. Ekström, Thomas Aref, Johan Runeson +3
The conversion efficiency of electric microwave signals into surface acoustic waves in different types of superconducting transducers is studied with the aim of quantum application…
Quantum Acoustics with Surface Acoustic Waves
Thomas Aref, Per Delsing, Maria K. Ekström +6
It has recently been demonstrated that surface acoustic waves (SAWs) can interact with superconducting qubits at the quantum level. SAW resonators in the GHz frequency range have a…
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…
