Mind the Gap: Anti-Critical Quantum Metrology
George Mihailescu, Karol Gietka·Feb 3, 2026
Critical quantum metrology exploits the dramatic growth of the quantum Fisher information near quantum phase transitions to enhance the precision of parameter estimation. This enhancement is commonly associated with a closing energy gap, which causes...
Evaluating Kubernetes Performance for GenAI Inference: From Automatic Speech Recognition to LLM Summarization
Sai Sindhur Malleni, Raúl Sevilla, Aleksei Vasilevskii +2 more·Feb 3, 2026
As Generative AI (GenAI), particularly inference, rapidly emerges as a dominant workload category, the Kubernetes ecosystem is proactively evolving to natively support its unique demands. This industry paper demonstrates how emerging Kubernetes-nativ...
Optimal Effective Hamiltonian for Quantum Computing and Simulation
Hao-Yu Guan, Xiao-Long Zhu, Yu-Hang Dang +1 more·Feb 3, 2026
The effective Hamiltonian serves as the conceptual pivot of quantum engineering, transforming physical complexity into programmable logic; yet, its construction remains compromised by the mathematical non-uniqueness of block diagonalization, which in...
Lee-Yang tensors and Hamiltonian complexity
Benjamin Wong, Sergey Bravyi, David Gosset +1 more·Feb 3, 2026
A complex tensor with $n$ binary indices can be identified with a multilinear polynomial in $n$ complex variables. We say it is a Lee-Yang tensor with radius $r$ if the polynomial is nonzero whenever all variables lie in the open disk of radius $r$. ...
Fluctuations of the inverted magnetic state and how to sense them
Anna-Luisa E. Römling, Artim L. Bassant, Rembert A. Duine·Feb 3, 2026
Magnons are the low-energy excitations of magnetically ordered materials. While the magnetic moment of a ferromagnet aligns with an applied magnetic field, it has been experimentally shown that the magnetic order can be inverted by injecting spin cur...
An Evaluation of the Remote CX Protocol under Noise in Distributed Quantum Computing
Leo Sünkel, Michael Kölle, Tobias Rohe +1 more·Feb 3, 2026
Quantum computers connected through classical and quantum communication channels can be combined to function as a single unit to run large quantum circuits that each device is unable to execute on their own. The distributed quantum computing paradigm...
Microscopic derivation of a completely positive master equation for the description of Open Quantum Brownian Motion of a particle in a potential
Ayanda Zungu, Ilya Sinayskiy, Francesco Petruccione·Feb 3, 2026
Open Quantum Brownian Motion (OQBM) was introduced as a scaling limit of discrete-time open quantum walks. This limit defines a new class of quantum Brownian motion, which incorporates both the external and internal degrees of freedom of the Brownian...
QRC-Lab: An Educational Toolbox for Quantum Reservoir Computing
Anderson Fernandes Pereira dos Santos·Feb 3, 2026
Quantum Reservoir Computing (QRC) has emerged as a strong pa- radigm for Noisy Intermediate-Scale Quantum (NISQ) machine learning, ena- bling the processing of temporal data with minimal training overhead by exploi- ting the high-dimensional dynamics...
Evaluating Quantum Wire Cutting for QAOA: Performance Benchmarks in Ideal and Noisy Environments
Michel Meulen, Niels M. P. Neumann, Jasper Verbree·Feb 3, 2026
Current quantum computers suffer from a limited number of qubits and high error rates, limiting practical applicability. Different techniques exist to mitigate these effects and run larger algorithms. In this work, we analyze one of these techniques ...
Quantum Circuit Generation via test-time learning with large language models
Adriano Macarone-Palmieri, Rosario Lo Franco·Feb 3, 2026
Large language models (LLMs) can generate structured artifacts, but using them as dependable optimizers for scientific design requires a mechanism for iterative improvement under black-box evaluation. Here, we cast quantum circuit synthesis as a clos...
Stationary entanglement of a levitated oscillator with an optical field
Q. Deplano, A. Pontin, F. Marino +1 more·Feb 3, 2026
Stationary entanglement between the motion of macroscopic objects and light is a long-standing goal of quantum optomechanics, with implications for both fundamental tests of quantum physics and emerging quantum technologies. We report the generation ...

Jeongbin Jo, Santanam Wishal, Shah Md Khalil Ullah +2 more·Feb 3, 2026
Quantum generative models offer a novel approach to exploring high-dimensional Hilbert spaces but face significant challenges in scalability and expressibility when applied to multi-modal distributions. In this study, we explore a Hybrid Quantum-Clas...
Zak phase and bulk-boundary correspondence in a generalized Dirac-Kronig-Penney model
Giuliano Angelone, Domenico Monaco, Gabriele Peluso·Feb 3, 2026
We investigate the topological properties of a generalized Dirac--Kronig--Penney model, a continuum one-dimensional model for a relativistic quantum chain. By tuning the coupling parameters this model can accommodate five Altland--Zirnbauer--Cartan s...
Stochastic Spiking Neuron Based SNN Can be Inherently Bayesian
Huannan Zheng, Jingli Liu, Kezhou Yang·Feb 3, 2026
Uncertainty in biological neural systems appears to be computationally beneficial rather than detrimental. However, in neuromorphic computing systems, device variability often limits performance, including accuracy and efficiency. In this work, we pr...

Kaito Kishi, Riki Toshio, Jun Fujisaki +3 more·Feb 3, 2026
In fault-tolerant quantum computing, soft outputs from real-time decoders play a crucial role in improving decoding accuracy, post-selecting magic states, and accelerating lattice surgery. A recent paper by Meister et al. [arXiv:2405.07433 (2024)] pr...
