Persistence of entangled states and high-fidelity quantum gate operations in Si/SiGe spin qubits at high temperature

We characterize single- and two-qubit operations in a SiGe quantum dot array, from the perspective of its quantum information processing capabilities. The analysis includes rigorous randomized benchmarking of single- and two-qubit gates, state preparation and measurement characte...

Beyond Accuracy: Pneumonia Severity Grading in Chest X-Rays Using RSNA 2018 Bounding-Box Extent Metadata and ViT

Chest X-ray pneumonia assessment is commonly formulated as a binary classification problem that does not explicitly represent radiographic burden. In this work, we reinterpret the RSNA 2018 Pneumonia Detection Challenge dataset by using expert bounding-box annotations to derive t...
