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...
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...
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...
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...
Skyrmion Quantum Diode Prototype: Bridging Micromagnetic Simulations and Quantum Models
Haowen Yang, Gerald Bissell, Han Zhong +4 more·Jan 16, 2026
Magnetic skyrmions are topologically protected spin textures known for their robustness against perturbations. Their topological stability makes them robust information carriers, ideal for tackling a key challenge in quantum computing: creating relia...
Controlled Parity of Cooper Pair Tunneling in a Hybrid Superconducting Qubit
David Feldstein-Bofill, Leo Uhre Jacobsen, Ksenia Shagalov +9 more·Jan 16, 2026
Superconducting quantum circuits derive their nonlinearity from the Josephson energy-phase relation. Besides the fundamental $\cosφ$ term, this relation can also contain higher Fourier harmonics $\cos(kφ)$ corresponding to correlated tunneling of $k$...
Noise-Aware Quantum Architecture Search Based on NSGA-II Algorithm
Chenlu Li, Hui Zeng, Dazhi Ding·Jan 16, 2026
Quantum architecture search (QAS) has emerged to automate the design of high-performance quantum circuits under specific tasks and hardware constraints. We propose a noise-aware quantum architecture search (NA-QAS) framework based on variational quan...
Quantum solver for single-impurity Anderson models with particle-hole symmetry
Mariia Karabin, Tanvir Sohail, Dmytro Bykov +8 more·Jan 15, 2026
Quantum embedding methods, such as dynamical mean-field theory (DMFT), provide a powerful framework for investigating strongly correlated materials. A central computational bottleneck in DMFT is in solving the Anderson impurity model (AIM), whose exa...
Hybrid superinductance with Al/InAs
Junseok Oh, Ido Levy, Tyler Cowan +4 more·Jan 15, 2026
We report microwave spectroscopy of Josephson junctions chains made from an epitaxial Al/InAs heterostructure. The chains exhibit superinductance, with characteristic wave impedance exceeding $R_{Q} = \hbar/(2e)^{2}$. The planar nature of the junctio...

Interface circuits are the key components that enable the hybrid integration of superconductor and semiconductor digital electronics. The design requirements of superconductor-semiconductor interface circuits vary depending on the application, such a...
Parallelizing the Variational Quantum Eigensolver: From JIT Compilation to Multi-GPU Scaling
Rylan Malarchick, Ashton Steed·Jan 15, 2026
The Variational Quantum Eigensolver (VQE) is a hybrid quantum-classical algorithm for computing ground state energies of molecular systems. We implement VQE to calculate the potential energy surface of the hydrogen molecule (H$_2$) across 100 bond le...
Emergent Nonperturbative Universal Floquet Localization
Soumadip Pakrashi, Atanu Rajak, Sambuddha Sanyal·Jan 14, 2026
We show that a robust, nonperturbative localization plateau emerges in periodically driven quasiperiodic lattices, independent of the static localization properties and drive protocol. Using exact Floquet dynamics, Floquet perturbation theory, and op...
