Multi-ion entangling gates mediated by spectrally unresolved modes
Modesto Orozco-Ruiz, Florian Mintert·Feb 11, 2026
Entangling interactions between distant qubits can be mediated via an additional degree of freedom. In conventional trapped-ion schemes, realizing a well-defined, coherent gate typically requires spectrally addressing a specific bus mode. As the ion ...
Quantum computing with anyons is fault tolerant
Anasuya Lyons, Benjamin J. Brown·Feb 11, 2026
In seminal work (arxiv:quant-ph/9707021) Alexei Kitaev proposed topological quantum computing (arXiv:cond-mat/0010440, arxiv:quant-ph/9707021, arXiv:quant-ph/0001108, arXiv:0707.1889), whereby logic gates of a quantum computer are conducted by creati...
Floquet Control of Electron and Exciton Transport in Kekulé-Distorted Graphene
Sita Kandel, Godfrey Gumbs·Feb 11, 2026
This work investigates the Floquet dynamics of electrons and excitons (particle-hole pairs) in a Dirac material referred to as Kekulé-distorted graphene. Specifically, we examine the role played by a high frequency driving electromagnetic field on th...
Recirculating Quantum Photonic Networks for Fast Deterministic Quantum Information Processing
Emil Grovn, Matias Bundgaard-Nielsen, Jesper Mørk +2 more·Feb 11, 2026
A fundamental challenge in photonics-based deterministic quantum information processing is to realize key transformations on time scales shorter than those of detrimental decoherence and loss mechanisms. This challenge has been addressed through devi...
Anyon Permutations in Quantum Double Models through Constant-depth Circuits
Yabo Li, Zijian Song·Feb 10, 2026
We provide explicit constant-depth local unitary circuits that realize general anyon permutations in Kitaev's quantum double models. This construction can be naturally understood through a correspondence between anyon permutation symmetries of two-di...
QSolver: A Quantum Constraint Solver
Shangzhou Xia, Haitao Fu, Jianjun Zhao·Feb 10, 2026
With the growing interest in quantum programs, ensuring their correctness is a fundamental challenge. Although constraint-solving techniques can overcome some limitations of traditional testing and verification, they have not yet been sufficiently ex...
Construction of the full logical Clifford group for high-rate quantum Reed-Muller codes using only transversal and fold-transversal gates
Theerapat Tansuwannont, Tim Chan, Ryuji Takagi·Feb 10, 2026
To build large-scale quantum computers while minimizing resource requirements, one may want to use high-rate quantum error-correcting codes that can efficiently encode information. However, realizing an addressable gate$\unicode{x2014}$a logical gate...
Error-mitigated quantum state tomography using neural networks
Yixuan Hu, Mengru Ma, Jiangwei Shang·Feb 10, 2026
The reliable characterization of quantum states is a fundamental task in quantum information science. For this purpose, quantum state tomography provides a standard framework for reconstructing quantum states from measurement data, yet it is often de...
Rigorous no-go theorems for heralded linear-optical state generation tasks
Deepesh Singh, Ryan J. Marshman, Luis Villegas-Aguilar +2 more·Feb 10, 2026
A major challenge in photonic quantum technologies is developing strategies to prepare suitable discrete-variable quantum states using simple input states, linear optics, and auxiliary photon measurements to identify successful outcomes. Fundamentall...
Efficient and deterministic high-dimensional controlled-swap gates on hybrid linear optical systems with high fidelity
Gui-Long Jiang, Jun-Bin Yuan, Wen-Qiang Liu +1 more·Feb 10, 2026
Implementation of quantum logic gates with linear optical elements plays a prominent role in quantum computing due to the relatively easier manipulation and realization. We present efficient schemes to implement controlled-NOT (CNOT) gate and control...
Surrogate-Guided Quantum Discovery in Black-Box Landscapes with Latent-Quadratic Interaction Embedding Transformers
Saisubramaniam Gopalakrishnan, Dagnachew Birru·Feb 10, 2026
Discovering configurations that are both high-utility and structurally diverse under expensive black-box evaluation and strict query budgets remains a central challenge in data-driven discovery. Many classical optimizers concentrate on dominant modes...
Negative Hybridization: a Potential Cure for Braiding with Imperfect Majorana Modes
Cole Peeters, Themba Hodge, Stephan Rachel·Feb 9, 2026
Majorana zero modes, the elementary building blocks for the quantum bits of topological quantum computers, are known to suffer from hybridization as their wavefunctions begin to overlap. This breaks the ground state degeneracy, splitting their energy...
Surface code off-the-hook: diagonal syndrome-extraction scheduling
Gilad Kishony, Austin Fowler·Feb 9, 2026
In the rotated surface code, hook errors (errors on auxiliary qubits midway through syndrome extraction that propagate to correlated two-qubit data errors) can reduce the circuit-level code distance by a factor of two if the extraction schedule is po...
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...
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...
Efficient circuit compression by multi-qudit entangling gates in linear optical quantum computation
Apurav, Jaskaran Singh·Feb 9, 2026
Linear optical quantum computation (LOQC) offers a promising platform for scalable quantum information processing, but its scalability is fundamentally constrained by the probabilistic nature of non-local entangling gates. Qudit circuit compression s...

BitLogic: Training Framework for Gradient-Based FPGA-Native Neural Networks
Simon Bührer, Andreas Plesner, Aczel Till +1 more·Feb 7, 2026
The energy and latency costs of deep neural network inference are increasingly driven by deployment rather than training, motivating hardware-specialized alternatives to arithmetic-heavy models. Field-Programmable Gate Arrays (FPGAs) provide an attra...
Symmetry and localisation in causally constrained quantum operator dynamics
Marcell D. Kovács, Christopher J. Turner, Lluís Masanes·Feb 6, 2026
This paper explores the connection between causality and many-body dynamics by studying the algebraic structure of tri-partite unitaries ('walls') which permanently arrest local operator spreading in their time-periodic evolution. We show that the re...
