title: Mixed Quantum States Datasets for Entanglement Classification

description: Dataset for Supervised Machine Learning Classification of Entanglement in Mixed Quantum States

This dataset is designed for the training and evaluation of supervised machine learning algorithms aimed at classifying quantum states. Specifically, the dataset contains labeled examples of 2-qubit and 3-qubit mixed quantum states, categorized as factorizable, separable, and entangled.

The data is provided in `.npy` format, compatible with common scientific computing libraries such as NumPy. Each sample represents a quantum state and is labeled according to its classification, enabling the development and benchmarking of models for quantum state discrimination.

Data Access and Structure

Upon loading, the dataset is structured as a dictionary with two main keys:

- 'matrices': contains the quantum state matrices, stored as NumPy arrays of dtype complex128;- 'labels': contains the corresponding classification labels.

Labeling Scheme





For general classification tasks, classes are ordered as: Fact (factorizable): 0 Sep (separable): 1 Ent (entangled): 2




For fine-grained labeling of separable classes (e.g., ['Ent', 'Fact', 'Sep_1', 'Sep_2', 'Sep_3']), classes are ordered as: 'Fact': 0 'Sep_1': 1 'Sep_2': 2 'Sep_3': 3 'Ent': 4

title: Orthomosaic Image and Digital Surface Model for the Kotzebue 3 Beaver Dams and Ponds site, Baldwin Peninsula, Alaska, 08 August 2023

description: The Arctic Beaver Observation Network (A-BON): Tracking a new disturbance regime project observes beaver engineering across circumarctic treeline and tundra environments during the last half-century by mapping and tracking beaver ponds using remote sensing imagery. Drones are being used to collect baseline data and track beaver dam building and pond evolution over time. This dataset consists of an orthomosaic and digital surface model (DSM) derived from drone surveys on 08 August 2023 at the Kotzebue 3 site on the Baldwin Peninsula, Alaska. 525 digital images were acquired from a DJI Phantom 4 Real-Time Kinematic (DJI P4RTK) quadcopter with a DJI D-RTK 2 Mobile Base Station. The mapped area was around 82 hectares (ha). The drone system was flown at 120 meters (m) above ground level (agl) and flight speeds varied from 8-9 meters/second (m/s). The orientation of the camera was set to 90 degrees (i.e. looking straight down). The along-track overlap and across-track overlap of the mission were set at 80% and 70%, respectively. All images were processed in the software Pix4D Mapper (v. 4.9.0) using the standard 3D Maps workflow and the accurate geolocation and orientation calibration method to produce the orthophoto mosaic and digital surface model at spatial resolutions of 5 and 10 centimeters (cm), respectively. Elevation information derived over waterbodies is noisy and does not represent the surface elevation of the feature. A Leica Viva differential global positioning system (GPS) provided ground control for the mission and the data were post-processed to WGS84 UTM Zone 3 North in Ellipsoid Heights (meters).

title: Cloud Vertical Structure

description: Active cloud observations from A-Train’s CloudSat and CALIPSO satellites offer new opportunities to examine the vertical structure of hydrometeor layers. We use the 2B-CLDCLASS-LIDAR merged CloudSat-CALIPSO product to examine global aspects of hydrometeor vertical stratification. We group the data into major cloud vertical structure (CVS) classes based on our interpretation of how clouds in three standard atmospheric layers overlap and provide their global frequency of occurrence.
