Tunable Nonlocal ZZ Interaction for Remote Controlled-Z Gates Between Distributed Fixed-Frequency Qubits

Yuan, Benzheng; Zhang, Chaojie; He, Haoran et al.

arXiv · 2026 · English · arXiv

Fault-tolerant quantum computing requires large-scale superconducting processors, yet monolithic architectures face increasing constraints from wiring density, crosstalk, and fabrication yield. Modular superconducting platforms offer a scalable alternative, but achieving high-fidelity entangling…

The Power of Power-of-SWAP: Postselected Quantum Computation with the Exchange Interaction

Burkat, Jędrzej; Strelchuk, Sergii; Studziński, Michał

arXiv · 2026 · English · arXiv

We introduce Exchange Quantum Polynomial Time (XQP) circuits, which comprise quantum computation using only computational basis SPAM and the isotropic Heisenberg exchange interaction. Structurally, this sub-universal model captures decoherence-free subspace computation without access to singlet…

Intelligent Radio Resource Slicing for 6G In-Body Subnetworks

Abdelrahman, Samira; Farag, Hossam

arXiv · 2026 · English · arXiv

6G In-body Subnetworks (IBSs) represent a key enabler for supporting standalone eXtended Reality (XR) applications. IBSs are expected to operate as an underlay to existing cellular networks, giving rise to coexistence challenges when sharing radio resources with other cellular users, such as…

Comparison of Origins of Re-Entrant Supercurrents at High In-Plane Magnetic Fields in Planar InAs-Al Josephson Junctions

Mudi, S. R.; Anupam, S.; Mourik, V. et al.

arXiv · 2026 · English · arXiv

Hybrid superconductor-semiconductor systems with large spin-orbit coupling are important platforms for realizing topological or triplet superconductivity. Planar Josephson junctions made using these materials are predicted to enter the topological state by tuning the phase difference between the…

Bifurcations of solitary waves in a coupled system of long and short waves

Hornick, James; Pelinovsky, Dmitry E.

arXiv · 2026 · English · arXiv

We consider families of solitary waves in the Korteweg--de Vries (KdV) equation coupled with the linear Schrödinger (LS) equation. This model has been used to describe interactions between long and short waves. To characterize families of solitary waves, we consider a sequence of local (pitchfork)…

Compressing Transformer Language Models via Matrix Product Operator Decomposition: A Case Study on PicoGPT

Javanmard, Younes; Pandit, Tanmoy; Mardani, Masoud

arXiv · 2026 · English · arXiv

Transformer-based language models achieve strong performance across NLP tasks, but their quadratic parameter scaling with hidden dimension makes deployment on resource-constrained hardware expensive. We study Matrix Product Operator (MPO) decomposition as a principled compression method for…

Thermodynamic Formalism for Quasimorphisms: Lattices in Higher Rank Semisimple Lie Groups

Carrasco, Pablo D.; Rodriguez-Hertz, Federico

arXiv · 2026 · English · arXiv

We give a proof, based on thermodynamic formalism, of a theorem in bounded cohomology extending a foundational result of Burger and Monod: if $Γ$ is an irreducible uniform lattice in a non-compact connected semisimple Lie group of real rank at least $2$, then for any finite-dimensional…

The conjecture of Colmez and reciprocity laws for modular forms

Maillot, Vincent; Rössler, Damian

arXiv · 2026 · English · arXiv

In an article published in 1993, P. Colmez formulated a remarkable conjecture, which asserts that the Faltings height of a CM abelian variety can be computed as a linear combination of logarithmic derivatives of Artin $L$-functions. Noting that the Faltings height is an average of transcendental…

From Hole Theory to Quantum Field Theory: Relativistic Fermions and the Role of Ettore Majorana (1933-1937)

Vissani, Francesco

arXiv · 2026 · English · arXiv

Between 1933 and 1937, the treatment of relativistic spin-1/2 particles, initially rooted in Hole theory, evolved into the modern framework of quantum field theory. This paper reconstructs the crucial stages of that transition by examining the formal and physical progress of the numerous authors…

Limit Bi-Shadowing for Semi-Hyperbolic Systems

Cheng, Linying; Guo, Haiye

arXiv · 2026 · English · arXiv

This paper investigates the shadowing properties in semi-hyperbolic systems. We introduce three classes of shadowing properties defined on families of manifolds, and prove that a semi-hyperbolic family possesses the $L^p$ bi-shadowing property, the limit bi-shadowing property, and the asymptotic…

Measuring Cross-Jurisdictional Transfer of Medical Device Risk Concepts with Explainable AI

Han, Yu; Ceross, Aaron

arXiv · 2026 · English · arXiv

Medical device regulators in the United States(FDA), China (NMPA), and Europe (EU MDR) all use the language of risk, but classify devices through structurally different mechanisms. Whether these apparently shared concepts carry transferable classificatory signal across jurisdictions remains…

Feel Robot Feels: Tactile Feedback Array Glove for Dexterous Manipulation

Jia, Feiyu; Niu, Xiaojie; Yang, Sizhe et al.

arXiv · 2026 · English · arXiv

Teleoperation is a key approach for collecting high-quality, physically consistent demonstrations for robotic manipulation. However, teleoperation for dexterous manipulation remains constrained by: (i) inaccurate hand-robot motion mapping, which limits teleoperated dexterity, and (ii) limited…

Which Functions Admit a Positive Geometry? From Branch Cuts to String Amplitudes

Kim, Hyungrok; Stalknecht, Jonah

arXiv · 2026 · English · arXiv

Positive geometry provides a geometric framework where physical observables are encoded as canonical forms associated to regions of kinematic space. In this paper we consider a generalisation to an infinite union of line segments, which allows us to capture canonical forms beyond rational…

Rational solutions for algebraic solitons in the massive Thirring model

Zhao, Zhen; He, Cheng; Feng, Baofeng et al.

arXiv · 2026 · English · arXiv

An algebraic soliton of the massive Thirring model (MTM) is expressed by the simplest rational solution of the MTM with the spatial decay of $\mathcal{O}(x^{-1})$. The corresponding potential is related to a simple embedded eigenvalue in the Kaup--Newell spectral problem. This work focuses on the…
