From 2D Yang-Mills to Calogero-Sutherland via a colored particle

Marcia Tenser, Amilcar R. Queiroz·Jun 11, 2026

We study Yang-Mills theory coupled to a particle on a cylinder, where gauge invariance and compactness reduce the dynamics to a finite dimensional quantum system. In the Abelian case, this yields a model equivalent to the Landau problem on a torus, w...

Representation-Induced Symmetry Trapping in Adaptive Variational Quantum Simulations of Multi-Reference Topologies

Hermawan Kresno Dipojono·Jun 11, 2026

Evaluating the trainability of adaptive quantum chemistry algorithms under multi-reference static correlation requires understanding how representation topologies intertwine with molecular geometry. We systematically expose a deep physical dependence...

Beyond the Unruh vacuum: multi-time correlations in black hole collapse and evaporation

Konstantinos Xenos, Charis Anastopoulos, Andreas F. Terzis·Jun 11, 2026

The black hole information paradox originates from the thermal character of Hawking radiation, which appears to erase information about the collapsing matter. However, thermality constrains only observables defined at a single time and leaves the str...

An LLM System for Autonomous Variational Quantum Circuit Design

Kenya Sakka, Wataru Mizukami, Kosuke Mitarai·Jun 11, 2026

The design of high performing quantum circuits remains largely dependent on human expertise. We introduce an autonomous agentic framework that employs large language models (LLMs) to conduct iterative quantum circuit designs under explicit design con...

Positional Encoding in the Context of Memristor-Based Analog Computation for Automatic Speech Recognition

Benedikt Hilmes, Nick Rossenbach, Ralf Schlüter·Jun 11, 2026

Memristors provide a new chance for resource-efficient computation of neural models for natural language processing by enabling analog execution of vector-matrix-multiplication. Yet, computations on these devices are currently subject to larger disto...

Steady-State Noise Signatures of Lindbladian Exceptional Points

Shihang Pan, Gianmichele Blasi, Géraldine Haack·Jun 11, 2026

Exceptional points (EPs) are non-Hermitian degeneracies at which two or more eigenvalues and their corresponding eigenvectors coalesce. In open quantum systems, exceptional points can arise in the Lindbladian governing the dissipative dynamics. Their...

Driven-dissipative entanglement of distant giant atoms

Aziza Almanakly, Ariadna Soro, Alejandro Vivas-Viaña +15 more·Jun 11, 2026

Quantum interconnects distribute entanglement via controlled light-matter interactions for quantum computing and sensing applications. Many entanglement generation schemes use coherent, reversible interactions that require precisely calibrated pulses...

Exploring Exotic Spin-Dependent Interactions Beyond the Standard Model: Theoretical Foundations and Experimental Investigations

L. Y. Wu, H. Yan·Jun 11, 2026

New interactions mediated by novel particles propose solutions to several important questions in modern physics. Axions serve as examples of such particles; they are lightweight and interact weakly with ordinary matter. This category of particles, in...

Understanding quantum behaviors of an electron in a uniform magnetic field alternatively

Jin-Ming Wang, Yuan-Zao Gao, Dai-Lin Cun +1 more·Jun 11, 2026

Quantum mechanically, an electron moving in a uniform magnetic field forms Landau levels. A curious feature is that for states with a negative angular quantum number, the total probability current vanishes, which appears to contradict the classical p...

Where a Quantum Reservoir Works: A Transferable Operating Band

Markus Baumann, Itamar Fink, Johannes Wittmann +2 more·Jun 11, 2026

In quantum reservoir computing, a fixed quantum system transforms an input signal, while learning reduces to training a simple linear readout on its measured outputs. Since the quantum dynamics themselves are never optimized, the method is well suite...

Kubo-Martin-Schwinger conditions for non-Hermitian systems

Chen Lan, Luyao Ma, Hao Yang·Jun 11, 2026

We investigate the extension of the Kubo--Martin--Schwinger (KMS) thermal equilibrium condition to non-Hermitian Hamiltonians with real spectra and biorthogonal eigensystems, providing a systematic analysis through three complementary routes. Our cen...

Coupling-Grouped XY-QAOA for Joint Anomaly-Feature Selection

Pauli Taipale·Jun 11, 2026

Selecting anomalous samples and explanatory features under fixed budgets defines a coupled constrained-optimization problem. Sequential feature-first selection ranks features before choosing samples, which can overlook features whose utility depends ...

LLM-as-an-Investigator: Evidence-First Reasoning for Robust Interactive Problem Diagnosis

Fabrizio Marozzo, Pietro Liò·Jun 11, 2026

Large language models (LLMs) are increasingly used as interactive assistants for technical problem solving. However, when users provide incomplete descriptions or plausible but unverified explanations, LLMs may prematurely align with these assumption...

Achieving Heisenberg limit under noisy conditions with quantum Zeno dynamics and dynamical decoupling

Ke Zeng, Bakmou Lahcen, Yu Jiang +1 more·Jun 11, 2026

Quantum Zeno dynamics (QZD) and dynamical decoupling (DD) are useful tools that enable the effective suppression of noise in quantum systems. We consider the problem of when (i) noise can be suppressed and (ii) Heisenberg limit (HL) can be achieved i...

Interference of critical dynamics associated with zero modes

Zhi-Han Zhang, Han-Chuan Kou, Peng Li·Jun 11, 2026

We study the interference of critical dynamics associated with zero modes (ICDZM) in the generalized Creutz ladders using closed quench paths that pass through two critical points successively. By reading out the final zero-mode transfer probability,...

Robust Pretty Good Measurement via Hybrid Classical-Quantum Pseudoinverse Approximation and Circuit-Level Realization

Bikash K. Behera, Andrés Camilo Granda Arango, Giuseppe Sergioli +1 more·Jun 11, 2026

Pretty Good Measurement (PGM) is a near-optimal strategy for quantum state discrimination, but its practical realization becomes unstable when the ensemble operator is singular or ill-conditioned. We introduce a numerically robust PGM formulation bas...
