Fidelity-Based Robustness Margins for Finite-Time Quantum Control
S. P. O'Neil, F. C. Langbein, C. A. Weidner +2
We develop a structure-specific fidelity-threshold robustness margin for finite-dimensional closed quantum systems under piecewise-constant coherent control. A scalar physical para…
The Sim-to-Real Gap in MRS Quantification: A Systematic Deep Learning Validation for GABA
Zien Ma, S. M. Shermer, Oktay KarakuÅ +1
Magnetic resonance spectroscopy (MRS) is used to quantify metabolites in vivo and estimate biomarkers for conditions ranging from neurological disorders to cancers. Quantifying low…
Energy Landscape Shaping for Robust Control of Atoms in Optical Lattices
C. A. Weidner, S. P. O'Neil, E. A. Jonckheere +2
Robust quantum control is crucial for realizing practical quantum technologies. Energy landscape shaping offers an alternative to conventional dynamic control, providing theoretica…
LATUP-Net: A Lightweight 3D Attention U-Net with Parallel Convolutions for Brain Tumor Segmentation
Ebtihal J. Alwadee, Xianfang Sun, Yipeng Qin +1
Early-stage 3D brain tumor segmentation from magnetic resonance imaging (MRI) scans is crucial for prompt and effective treatment. However, this process faces the challenge of prec…
