Trainability-Oriented Hybrid Quantum Regression via Geometric Preconditioning and Curriculum Optimization
Qingyu Meng, Yangshuai Wang·Jan 17, 2026
Quantum neural networks (QNNs) have attracted growing interest for scientific machine learning, yet in regression settings they often suffer from limited trainability under noisy gradients and ill-conditioned optimization. We propose a hybrid quantum...
Impact of Circuit Depth versus Qubit Count on Variational Quantum Classifiers for Higgs Boson Signal Detection
Fatih Maulana·Jan 17, 2026
High-Energy Physics (HEP) experiments, such as those at the Large Hadron Collider (LHC), generate massive datasets that challenge classical computational limits. Quantum Machine Learning (QML) offers a potential advantage in processing high-dimension...
Indoor Occupancy Classification using a Compact Hybrid Quantum-Classical Model Enabled by a Physics-Informed Radar Digital Twin
Sebastian Ratto, Ahmed N. Sayed, Neda Rojhani +6 more·Jan 17, 2026
Indoor occupancy classification enables privacy-preserving monitoring in settings such as remote elder care, where presence information helps triage alarms without cameras or wearables. Radar suits this role by sensing motion through occlusions and i...
Scalable and telecom single-erbium system with record-long room-temperature quantum coherence
Alex Kaloyeros, Natasha Tabassum, Spyros Gallis·Jan 17, 2026
Eliminating cryogenic operating requirements while preserving microsecond-scale quantum coherence and enabling CMOS scalability remains a central challenge for telecom quantum technologies. Addressing this, we introduce a CMOS-compatible quantum syst...
Any local Hamiltonian with ferromagnetic quantum many-body scars has a generalized Shiraishi-Mori form
Keita Omiya·Jan 16, 2026
Quantum many-body scars (QMBS) are nonthermal eigenstates embedded in otherwise thermal spectra. A broad class of exact QMBS is realized as fixed-momentum magnon states above a ferromagnetic reference state. Here we prove a structural theorem for thi...
Quantum Kernel Machine Learning for Autonomous Materials Science
Felix Adams, Daiwei Zhu, David W. Steuerman +2 more·Jan 16, 2026
Autonomous materials science, where active learning is used to navigate large compositional phase space, has emerged as a powerful vehicle to rapidly explore new materials. A crucial aspect of autonomous materials science is exploring new materials u...
Entanglement Distribution over a Polarization-Stabilized Aerial Fiber
Yicheng Shi, Jing Su, Anouar Rahmouni +9 more·Jan 16, 2026
We experimentally demonstrate the distribution of polarization-entangled photons across a 62-km, partially-aerial fiber. With polarization stabilization applied to the fiber link, we achieve a photon pair rate of approximately 1500 per second and obs...
Multiary gradings
Steven Duplij·Jan 16, 2026
This article develops a comprehensive theory of multiary graded polyadic algebras, extending the classical concept of group-graded algebras to higher-arity structures. We introduce the notion of grading by multiary groups and investigate various comp...
Homogeneous Microwave Delivery for Quantum Sensing with Nitrogen-Vacancy Centers at High Pressures
Timothy A. Elmslie, Luca Basso, Adam Dodson +2 more·Jan 16, 2026
Nitrogen vacancy (NV) centers have been demonstrated as a useful tool in high pressure environments. However, the geometry and small working area of the diamond anvil cells (DACs) used to apply pressure present a challenge to effective delivery of mi...
Experimental observation of dynamical blockade between transmon qubits via ZZ interaction engineering
Marco Riccardi, Aviv Glezer Moshe, Guido Menichetti +13 more·Jan 16, 2026
We report the experimental realization of strong longitudinal (ZZ) coupling between two superconducting transmon qubits achieved solely through capacitive engineering. By systematically varying the qubit frequency detuning, we measure cross-Kerr inte...
Meeting the Needs of the Global Quantum Science Community: A Call to Action
Tzula B. Propp, Brandy Todd, Sara A. Metwalli +8 more·Jan 16, 2026
2025 marks one hundred years since the discovery of quantum mechanics. In the century since then, quantum science has blossomed into a global community composed of academics, engineers, developers, and entrepreneurs. The world is currently in the mid...
Convergence Properties of Good Quantum Codes for Classical Communication
Alptug Aytekin, Mohamed Nomeir, Lei Hu +1 more·Jan 16, 2026
An important part of the information theory folklore had been about the output statistics of codes that achieve the capacity and how the empirical distributions compare to the output distributions induced by the optimal input in the channel capacity ...
Heat, work, and fluctuations in a driven quantum resonator
Riya Baruah, Pedro Portugal, Jun-Zhe Chen +2 more·Jan 16, 2026
A central building block of a heat engine is the working fluid, which mediates the conversion of heat into work. In nanoscale heat engines, the working fluid can be a quantum system whose behavior and dynamics are non-classical. A particularly versat...
Coupling free electrons to a trapped-ion quantum computer
Elias Pescoller, Santiago Beltrán-Romero, Sebastian Egginger +10 more·Jan 16, 2026
Freely propagating electrons may serve as quantum probes that can become coherently correlated with other quantum systems, offering access to advanced metrological resources. We propose a setup that coherently couples free electrons in an electron mi...
Noisy Analysis of Quantum SMOTE on Condition Monitoring and Fault Classification in Industrial and Energy Systems
Amit S. Patel, Himanshukumar R. Patel, Bikash K. Behera·Jan 16, 2026
Imbalanced datasets are a fundamental issue in industrial condition monitoring and fault classification pipelines, causing classical machine learning models to overfit the majority classes while failing to learn the minority fault patterns. This work...
Simulating Quantum Walk Hamiltonians without Pauli Decomposition
Mostafa Atallah, Alvin Gonzales, Daniel Dilley +3 more·Jan 16, 2026
In this work, we present a new algorithm for generating quantum circuits that efficiently implement continuous time quantum walks on arbitrary simple sparse graphs. The algorithm, called matching decomposition, works by decomposing a continuous-time ...
Quantum-enhanced optimization for patient stratification in clinical trials
Laia Domingo, Christine Johnson·Jan 16, 2026
Clinical trials are notorious for their high failure rates and steep costs, leading to wasted time and resources spend, prolonged development timelines, and delayed patient access to new therapies. A key contributor to these failures is biological un...
