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,...
Modern analog computing for solving differential and matrix equations
Zhong Sun, Piergiulio Mannocci, Manuel Le Gallo +1 more·Jun 11, 2026
In recent years, driven by the computational demands of data-intensive applications such as artificial intelligence and scientific computing, analog computing has gained renewed interest. Given the diversity of computational tasks and recent advancem...
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...
Hamiltonian-Aware ADAPT Variational Quantum Eigensolver for Molecular Ground-State Simulation
Runhong He, Chao Liu, Xin Hong +5 more·Jun 11, 2026
Designing compact ansätze in Variational Quantum Eigensolver (VQE) is crucial for solving energetic problems of practical molecules on near-term quantum devices. However, existing Adaptive Derivative-Assembled Pseudo-Trotter (ADAPT) ansätze face two ...
Reservoir-controlled electromagnetically induced gratings in a weakly driven two-level medium
Amjad Hussain, Hamid Arian Zad, Amjad Sohail +3 more·Jun 11, 2026
We theoretically investigate the transmission and diffraction of a weak probe field from an electromagnetically induced grating formed in a weakly driven two-level medium coupled to engineered quantum reservoirs. Using a perturbative solution of the ...

Miriam J. Leonhardt, Kai Müller, Oliver Lunt +1 more·Jun 11, 2026
Ultracold atoms in multimode optical cavities provide a rich testbed for many-body phenomena enabled by light-mediated interactions. Recent experiments include realizations of spin glasses and associative memories, as described by multimode Dicke mod...
