Parameterized Quantum Circuits as Feature Maps: Representation Quality and Readout Effects in Multispectral Land-Cover Classification
Ralntion Komini, Aikaterini Mandilara, Georgios Maragkopoulos +1
We investigate variational quantum classifiers (VQCs) for land-cover classification from multispectral satellite imagery, adopting a feature-map perspective in which the quantum ci…
Quantum-Inspired Unitary Pooling for Multispectral Satellite Image Classification
Georgios Maragkopoulos, Aikaterini Mandilara, Ralntion Komini +1
Multispectral satellite imagery poses significant challenges for deep learning models due to the high dimensionality of spectral data and the presence of structured correlations ac…
Feature Ranking in Credit-Risk with Qudit-Based Networks
Georgios Maragkopoulos, Lazaros Chavatzoglou, Aikaterini Mandilara +1
In finance, predictive models must balance accuracy and interpretability, particularly in credit risk assessment, where model decisions carry material consequences. We present a qu…
A Measurement Device Independent Quantum Key Distribution protocol in the service of three users
N. Stefanakos, G. Maragkopoulos, A. Mandilara +1
Quantum Key Distribution (QKD) is the only theoretically proven method for secure key distribution between two users. In this work, we propose and analyze a Measurement Device Inde…
Applications of Hybrid Machine Learning Methods to Large Datasets: A Case Study
G. Maragkopoulos, N. Stefanakos, A. Mandilara +1
We combine classical and quantum Machine Learning (ML) techniques to effectively analyze long time-series data acquired during experiments. Specifically, we demonstrate that replac…
