Multiplexed microwave resonators by frequency comb spectroscopy
Angelo Greco, Jukka-Pekka Kaikkonen, Luca Chirolli +4 more·Feb 9, 2026
Coplanar waveguide resonators are central to the thriving field of circuit quantum electrodynamics. Recently, we have demonstrated the generation of a broadband microwave-frequency comb spectrum using a superconducting quantum interference device (SQ...
Error compensation without a time penalty: robust spin-lock-induced crossing in solution NMR
Mohamed Sabba, Christian Bengs, Urvashi D. Heramun +1 more·Feb 9, 2026
A modification of the widely-used spin-lock-induced crossing (SLIC) procedure is proposed for the solution nuclear magnetic resonance (NMR) of strongly coupled nuclear spin systems, including singlet NMR and parahydrogen-enhanced hyperpolarised NMR e...
Quantum Riemannian Cubics with Obstacle Avoidance for Quantum Geometric Model Predictive Control
Leonardo Colombo·Feb 9, 2026
We propose a geometric model predictive control framework for quantum systems subject to smoothness and state constraints. By formulating quantum state evolution intrinsically on the projective Hilbert space, we penalize covariant accelerations to ge...
Differentiable Logical Programming for Quantum Circuit Discovery and Optimization
Antonin Sulc·Feb 9, 2026
Designing high-fidelity quantum circuits remains challenging, and current paradigms often depend on heuristic, fixed-ansatz structures or rule-based compilers that can be suboptimal or lack generality. We introduce a neuro-symbolic framework that ref...
ZK-Rollup for Hyperledger Fabric: Architecture and Performance Evaluation
Sania Siddiqui, Neha, Hari Babu K·Feb 9, 2026
A big challenge posed in blockchain centric platforms is achieving scalability while also preserving user privacy. This report details the design, implementation and evaluation of a Layer-2 scaling solution for Hyperledger Fabric using Zero Knowledge...
A cavity-mediated reconfigurable coupling scheme for superconducting qubits
Shinyoung Hwang, Sangyeon Lee, Eunjong Kim·Feb 9, 2026
Superconducting qubits have achieved remarkable progress in gate fidelity and coherence, yet their typical nearest-neighbor connectivity presents constraints for implementing complex quantum circuits. Here, we introduce a cavity-mediated coupling arc...
High-brightness fiber-based Sagnac source of entangled photon pairs for multiplexed quantum networks
Tess Troisi, Yoann Pelet, Romain Dalidet +4 more·Feb 9, 2026
A fully fibered source of entangled photon pairs based on a nonlinear Sagnac interferometer is reported. Operating at telecom wavelengths, the source relies exclusively on standard fiber-optic components and periodically poled lithium niobate (PPLN) ...
Spin-active chlorine-related centers in 4H-SiC with telecom-band emissions
Danial Shafizadeh, Misagh Ghezellou, Viktor M. Bobal +5 more·Feb 9, 2026
A photoluminescence (PL) and magnetic resonance investigation of a defect in chlorine-implanted 4H-SiC is presented. This Cl-related center emits light at telecom wavelengths with zero-phonon lines in the range 1350-1540 nm. Its four configurations e...
High-Probability Heralded Entanglement via Repeated Spin-Photon Phase Encoding with Moderate Cooperativity
Yu Liu, Martin B. Plenio·Feb 9, 2026
We propose a heralded high-probability scheme to generate remote entanglement between moderate-cooperativity spin-cavity registers with high fidelity. In conventional single-shot interfaces, limited cooperativity restricts the spin-conditional optica...
The equivalence of quantum deletion and insertion errors on permutation-invariant codes
Lewis Bulled, Yingkai Ouyang·Feb 9, 2026
Quantum synchronisation errors are a class of quantum errors that change the number of qubits in a quantum system. The classical error correction of synchronisation errors has been well-studied, including an insertion-deletion equivalence more than a...
Heterogeneous Optically-Detected Spin-Acoustic Resonance in Solid-State Molecular Thin-film
Kuan-Cheng Chen, Yongqiang Wen, Xiaotian Xu +7 more·Feb 9, 2026
We report an implementation of spin-acoustic resonance in pentacene thin films integrated on a high-quality-factor (high-Q) surface acoustic wave (SAW) resonator on a lithium niobate substrate. Heterogeneous optically detected spin-acoustic resonance...
Technosocial risks of ideal emotion recognition technologies: A defense of the (social) value of emotional expressions
Alexandra Pregent·Feb 9, 2026
The prospect of AI systems that I call ideal emotion recognition technologies (ERTs) is often defended on the assumption that social life would benefit from increased affective transparency. This paper challenges that assumption by examining the tech...
Non-Hermitian Renormalization Group from a Few-Body Perspective
Hiroyuki Tajima, Masaya Nakagawa, Haozhao Liang +1 more·Feb 9, 2026
Non-Hermiticity plays a fundamental role in open quantum systems and describes a wide variety of effects of interactions with environments, including quantum measurement. However, understanding its consequences in strongly interacting systems is stil...
Weak forms offer strong regularisations: how to make physics-informed (quantum) machine learning more robust
Annie E. Paine, Smit Chaudhary, Antonio A. Gentile·Feb 9, 2026
Physics-informed (PI) methodologies have surged to become a pillar route to solve Differential Equations (DEs), sustained by the growth of machine learning methods in scientific contexts. The main proposition of PI is to minimise variationally a loss...
Quantum thermodynamics in nonequilibrium
Md Manirul Ali, Po-Wen Chen·Feb 9, 2026
Understanding thermodynamics far from equilibrium at the quantum scale remains a fundamental challenge, particularly in the presence of quantum coherence. Here we develop a first-principles framework for nonequilibrium quantum thermodynamics by integ...
Quantum Optimization for Access Point Selection Under Budget Constraint
Mohamed Khalil Brik, Ahmed Shokry, Moustafa Youssef·Feb 9, 2026
Optimal Access Point (AP) selection is crucial for accurate indoor localization, yet it is constrained by budget, creating a trade-off between localization accuracy and deployment cost. Classical approaches to AP selection are often computationally e...
Quantum Wasserstein isometries of the $n$-qubit state space: a Wigner-type result
Gergely Bunth, Eszter Szabó, Dániel Virosztek·Feb 9, 2026
We determine the isometry group of the $n$-qubit state space with respect to the quantum Wasserstein distance induced by the so-called symmetric transport cost for all $n \in \mathbb{N}.$ It turns out that the isometries are precisely the Wigner symm...
Representation theory of inhomogeneous Gaussian unitaries
Jingqi Sun, Joshua Combes, Lucas Hackl·Feb 9, 2026
Gaussian unitaries, generated by quadratic Hamiltonians, are fundamental in quantum optics and continuous-variable computing. Their structures correspond to symplectic (bosons) and orthogonal (fermions) groups, but physical realizations give rise to ...

Quantum battery, as a novel energy storage device, offers the potential for unprecedented efficiency and performance beyond the capabilities of classical systems, with broad implications for future quantum technologies. Here, we experimentally \RefC{...
Time resolution at the quantum limit of two incoherent sources based on frequency resolved two-photon-interference
Salvatore Muratore, Vincenzo Tamma·Feb 9, 2026
The Rayleigh criterion is a widely known limit in the resolution of incoherent sources with classical measurements in the spatial domain. Unsurprisingly the estimation of the time delay between two weak incoherent signals is afflicted by an analogue ...
