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…
Precise in-situ tuning of a superconducting nanowire's critical current using high bias voltage pulses
Thomas Aref, Alexey Bezryadin
We present a method for in-situ tuning the critical current (or switching current) and critical temperature of a superconducting nanowire using high bias voltage pulses. Our main f…
