Limitations for adaptive quantum state tomography in the presence of detector noise
Adrian Skasberg Aasen, Martin Gärttner·Jan 7, 2026
Assumption-free reconstruction of quantum states from measurements is essential for benchmarking and certifying quantum devices, but it remains difficult due to the extensive measurement statistics and experimental resources it demands. An approach t...
Experimental Evaluation of a UAV-Mounted LEO Satellite Backhaul for Emergency Connectivity
Mattia Figaro, Francesco Rossato, Alexander Bonora +3 more·Jan 7, 2026
Reliable connectivity is critical for Public Protection and Disaster Relief operations, especially in rural or compromised environments where terrestrial infrastructure is unavailable. In such scenarios, NTNs, and specifically UAVs, are promising can...
Quantum Monte Carlo Simulations for predicting electron-positron pair production via the linear Breit-Wheeler process
Lucas I. Iñigo Gamiz, Óscar Amaro, Efstratios Koukoutsis +1 more·Jan 7, 2026
Quantum computing (QC) has the potential to revolutionise the future of scientific simulations. To harness the capabilities that QC offers, we can integrate it into hybrid quantum-classical simulations, which can boost the capabilities of supercomput...
Phases of the $q$-deformed $\mathrm{SU}(N)$ Yang-Mills theory at large $N$
Tomoya Hayata, Yoshimasa Hidaka, Hiromasa Watanabe·Jan 7, 2026
We investigate the $(2+1)$-dimensional $q$-deformed $\mathrm{SU}(N)_k$ Yang-Mills theory in the lattice Hamiltonian formalism, which is characterized by three parameters: the number of colors $N$, the coupling constant $g$, and the level $k$. By trea...
Iterative Matrix Product State Simulation for Scalable Grover's Algorithm
Mei Ian Sam, Tzu-Ling Kuo, Tai-Yue Li·Jan 7, 2026
Grover's algorithm is a cornerstone of quantum search algorithm, offering quadratic speedup for unstructured problems. However, limited qubit counts and noise in today's noisy intermediate-scale quantum (NISQ) devices hinder large-scale hardware vali...
Quantum vs. Classical Machine Learning: A Benchmark Study for Financial Prediction
Rehan Ahmad, Muhammad Kashif, Nouhaila Innan +1 more·Jan 7, 2026
In this paper, we present a reproducible benchmarking framework that systematically compares QML models with architecture-matched classical counterparts across three financial tasks: (i) directional return prediction on U.S. and Turkish equities, (ii...
Interference-Induced Suppression of Doublon Transport and Prethermalization in the Extended Bose-Hubbard Model
Zhen-Ting Bao, Kai Xu, Heng Fan·Jan 7, 2026
The coherent mobility of doublons, arising from second-order virtual dissociation-recombination processes, fundamentally limits their use as information carriers in the strongly interacting Bose-Hubbard model. We propose a disorder-free suppression m...
Transmutation based Quantum Simulation for Non-unitary Dynamics
Shi Jin, Chuwen Ma, Enrique Zuazua·Jan 7, 2026
We present a quantum algorithm for simulating dissipative diffusion dynamics generated by positive semidefinite operators of the form $A=L^\dagger L$, a structure that arises naturally in standard discretizations of elliptic operators. Our main tool ...
Many-body Quantum Score: a scalable benchmark for digital and analog quantum processors and first test on a commercial neutral atom device
Harold Erbin, Pierre-Louis Burdeau, Corentin Bertrand +2 more·Jan 6, 2026
We propose the Many-body Quantum Score (MBQS), a practical and scalable application-level benchmark protocol designed to evaluate the capabilities of quantum processing units (QPUs)--both gate-based and analog--for simulating many-body quantum dynami...
Time-Dependent Dunkl-Pauli Oscillator in the Presence of the Aharonov-Bohm Effect
Boubakeur Khantoul, Ahmed Tedjani·Jan 6, 2026
We present an exact, time-dependent solution for a two-dimensional Pauli oscillator deformed by Dunkl operators in the presence of an Aharonov--Bohm (AB) flux. By replacing conventional momenta with Dunkl momenta and allowing arbitrary time dependenc...

Silvano Cortesi, Lukas Schulthess, Davide Plozza +2 more·Jan 6, 2026
Indoor localization systems face a fundamental trade-off between efficiency and responsiveness, which is especially important for emerging use cases such as mobile robots operating in GPS-denied environments. Traditional RTLS either require continuou...
A Unified Frequency Principle for Quantum and Classical Machine Learning
Rundi Lu, Ruiqi Zhang, Weikang Li +3 more·Jan 6, 2026
Quantum neural networks constitute a key class of near-term quantum learning models, yet their training dynamics remain not fully understood. Here, we present a unified theoretical framework for the frequency principle (F-principle) that characterize...
