Tensor network approaches for learning non-linear dynamical laws
A. GoeÃmann, M. Götte, I. Roth +3
Given observations of a physical system, identifying the underlying non-linear governing equation is a fundamental task, necessary both for gaining understanding and generating det…
A quantum inspired approach to learning dynamical laws from data -- block-sparsity and gauge-mediated weight sharing
J. Fuksa, M. Götte, I. Roth +1
Recent years have witnessed an increased interest in recovering dynamical laws of complex systems in a largely data-driven fashion under meaningful hypotheses. In this work, we pro…
Noise-mitigated randomized measurements and self-calibrating shadow estimation
E. Onorati, J. Kitzinger, J. Helsen +4
Randomized measurements are increasingly appreciated as powerful tools to estimate properties of quantum systems, e.g., in the characterization of hybrid classical-quantum computat…
Quantum certification and benchmarking
J. Eisert, D. Hangleiter, N. Walk +5
Concomitant with the rapid development of quantum technologies, challenging demands arise concerning the certification and characterization of devices. The promises of the field ca…
Observation of relativistic electron microbursts in conjunction with intense radiation belt whistler-mode waves
K. Kersten, C. A. Cattell, A. Breneman +7
We present multi-satellite observations indicating a strong correlation between large amplitude radiation belt whistler-mode waves and relativistic electron precipitation. On separ…
Hierarchical restricted isometry property for Kronecker product measurements
I. Roth, A. Flinth, R. Kueng +2
Hierarchically sparse signals and Kronecker product structured measurements arise naturally in a variety of applications. The simplest example of a hierarchical sparsity structure…

V. Abrol, O. Absil, P. -A. Absil +58
The third edition of the "international - Traveling Workshop on Interactions between Sparse models and Technology" (iTWIST) took place in Aalborg, the 4th largest city in Denmark s…
Experimentally exploring compressed sensing quantum tomography
A. Steffens, C. Riofrio, W. McCutcheon +6
In the light of the progress in quantum technologies, the task of verifying the correct functioning of processes and obtaining accurate tomographic information about quantum states…
The near surface vertical atmospheric electric field abnormality could be as a promising imminent precursor of major earthquakes
T. Chen, H. Wu, X. -X. Zhang +27
A promising short term precursor of major earthquakes (EQ) is very crucial in saving people and preventing huge losses. Ez, atmospheric electrostatic field vertical component, unde…
Estimating gate-set properties from random sequences
J. Helsen, M. Ioannou, J. Kitzinger +4
With quantum computing devices increasing in scale and complexity, there is a growing need for tools that obtain precise diagnostic information about quantum operations. However, c…
Hourly Warning for Strong Earthquakes
T. Chen, L. Li, X. -X. Zhang +53
A promising perspective is presented that humans can provide hourly warning for strong land earthquakes (EQs, Ms6). Two important atmospheric electrostatic signal features are desc…
