Unsupervised quantum machine learning for fraud detection
Oleksandr Kyriienko, Einar B. Magnusson
We develop quantum protocols for anomaly detection and apply them to the task of credit card fraud detection (FD). First, we establish classical benchmarks based on supervised and…
Surface acoustic wave resonators in the quantum regime
R. Manenti, M. J. Peterer, A. Nersisyan +3
We present systematic measurements of the quality factors of surface acoustic wave (SAW) resonators on ST-X quartz in the gigahertz range at a temperature of . W…
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…
Excitation and detection of propagating spin waves at the single magnon level
Alexy D. Karenowska, Andrew D. Patterson, Michael J. Peterer +2
Ferro- and ferrimagnets play host to small-signal, microwave-frequency magnetic excitations called spin waves, the quanta of which are known as magnons. Over the last decade, the f…
Surface acoustic wave devices on bulk ZnO at low temperature
Einar B. Magnusson, Benjamin H. Williams, Riccardo Manenti +5
Surface acoustic wave (SAW) devices based on thin films of ZnO are a well established technology. However, SAW devices on bulk ZnO crystals are not practical at room temperature du…
Functional renormalization group approach to the singlet-triplet transition in quantum dots
E. B. Magnusson, N. Hasselmann, I. A. Shelykh
We present a functional renormalization group approach to the zero bias transport properties of a quantum dot with two different orbitals and in presence of Hund's coupling. Tuning…
