Effect of slowly decaying long-range interactions on topological qubits
Etienne Granet, Michael Levin·Dec 2, 2025
We study the robustness of topological ground state degeneracy to long-range interactions in quantum many-body systems. We focus on slowly decaying two-body interactions that scale like a power-law $1/r^α$ where $α$ is smaller than the spatial dimens...
Intrinsic Second-Order Topological Superconductors with Tunable Majorana Zero Modes
Xiao-Jiao Wang, Yijie Mo, Zhi Wang +2 more·Dec 2, 2025
Dirac semimetals, with their protected Dirac points, present an ideal platform for realizing intrinsic topological superconductivity. In this work, we investigate superconductivity in a two-dimensional, square-lattice nonsymmorphic Dirac semimetal. I...
Improved Ising Meson Spectroscopy Simulation on a Noisy Digital Quantum Device
Hao-Ti Hung, Isabel Nha Minh Le, Johannes Knolle +1 more·Dec 2, 2025
The transverse-field Ising model serves as a paradigm for studying confinement and excitation spectra, particularly the emergence of $E_8$ symmetry near criticality. However, experimentally resolving the Ising meson spectroscopy required to verify th...
Su-Schrieffer-Heeger model driven by sequences of two unitaries: periodic, quasiperiodic and random protocols
Maitri Ganguli, Diptiman Sen·Dec 2, 2025
We study the effect of driving the Su-Schrieffer-Heeger model using two unitary operators $U_1$ and $U_2$ in different combinations; the unitaries differ in the values of the inter-cell hopping amplitudes. Specifically, we study the cases where the u...
Quantum Coulomb drag signatures of Majorana bound states
Zi-Wei Li, Jiaojiao Chen, Wei Xiong +2 more·Dec 2, 2025
Majorana bound states (MBSs), with their non-Abelian statistics and topological protection, are key candidates for fault-tolerant quantum computation. However, their unambiguous identification in solid-state systems remains a fundamental challenge. H...
Generalizing fusion rules by shuffle: Symmetry-based classifications of nonlocal systems constructed from similarity transformations
Yoshiki Fukusumi, Taishi Kawamoto·Dec 1, 2025
We study fusion rings, or symmetry topological field theories (SymTFTs), which lie outside the non-negative integer matrix representation (NIM-rep), by combining knowledge from generalized symmetry and that from pseudo-Hermitian systems. By applying ...
Anomalies on the Lattice, Homotopy of Quantum Cellular Automata, and a Spectrum of Invertible States
Alexander M. Czajka, Roman Geiko, Ryan Thorngren·Dec 1, 2025
We develop a rigorous topological theory of anomalies on the lattice, which are obstructions to gauging global symmetries and the existence of trivial symmetric states. We also construct $Ω$-spectra of a class of invertible states and quantum cellula...
Fixed Points in Quantum Metric Spaces: A Structural Advantage over Fuzzy Frameworks
Nicola Fabiano·Dec 1, 2025
We prove an existence and uniqueness theorem for fixed points of contraction maps in the framework of quantum metric spaces, where distinguishability is defined by the $L^2$ norm: $d_Q(ψ_1,ψ_2) = \|ψ_1 - ψ_2\|$. The result applies to normalized real-...
Experimental Witness of Quantum Jump Induced High-Order Liouvillian Exceptional Points
Zhuo-Zhu Wu, Pei-Dong Li, Tai-Hao Cui +11 more·Dec 1, 2025
The exceptional point has presented considerably interesting and counterintuitive phenomena associated with nonreciprocity, precision measurement, and topological dynamics. The Liouvillian exceptional point (LEP), involving the interplay of energy lo...
From Betti Numbers to Persistence Diagrams: A Hybrid Quantum Algorithm for Topological Data Analysis
Dong Liu·Dec 1, 2025
Persistence diagrams serve as a core tool in topological data analysis, playing a crucial role in pathological monitoring, drug discovery, and materials design. However, existing quantum topological algorithms, such as the LGZ algorithm, can only eff...
Tailoring Bell inequalities to the qudit toric code and self testing
Eloïc Vallée, Owidiusz Makuta, Patrick Emonts +2 more·Nov 28, 2025
Bell nonlocality provides a robust scalable route to the efficient certification of quantum states. Here, we introduce a general framework for constructing Bell inequalities tailored to the $\mathbb{Z}_d$ toric code for odd prime local dimensions. Se...
Probing the Fermi Sea Topology in a Quantum Gas
Cyprien Daix, Pok Man Tam, Maxime Dixmerias +5 more·Nov 28, 2025
Pauli's exclusion principle forces fermions to occupy distinct quantum states, creating a filled region of momentum space at low temperature, the Fermi sea, whose topology governs the system's response to perturbations and the nature of its correlati...
Controlling Dissipative Topology Through Floquet Driving: From Transient Diagnostics to Boundary States Isolation
Koustav Roy, Shahroze Shahab, Saurabh Basu·Nov 28, 2025
Engineering dissipative dynamics in open quantum systems is under active focus, especially in topological settings where resilient edge modes are expected to exhibit decay rates distinct from the bulk. In this letter, we propose an efficient dynamica...
Quantum spectroscopy of topological dynamics via a supersymmetric Hamiltonian
Hiroshi Yamauchi, Satoshi Kanno, Yuki Sato +4 more·Nov 28, 2025
Topological data analysis (TDA) characterizes complex dynamics through global invariants, but classical computation becomes prohibitive for high-dimensional data. We reinterpret time-domain dynamics as the eigenvalue spectrum of a supersymmetric (SUS...
Nonlinear Odd Viscoelastic Effect
Ashwat Jain, Wojciech J. Jankowski, M. Mehraeen +1 more·Nov 27, 2025
We uncover a class of nonlinear odd viscoelastic effects in three spatial dimensions. We show that these dissipationless effects arise upon combining strains in two orthogonal directions, yielding momentum flow in the third direction. We demonstrate ...
Deconstructing symmetry breaking dynamics
Fumika Suzuki, Wojciech H. Zurek·Nov 27, 2025
The Kibble-Zurek mechanism (KZM) successfully predicts the density of topological defects deposited by the phase transitions, but it is not clear why. Its key conjecture is that, near the critical point of the second-order phase transition, critical ...
Twisted (co)homology of non-orientable Weyl semimetals
Thijs Douwes, Marcus Stålhammar·Nov 27, 2025
The quasi-particle excitations in Weyl semimetals, known as Weyl fermions, are usually forced to emerge in charge-conjugate pairs by the Nielsen--Ninomiya theorem. When the Brillouin zone is non-orientable, this constraint is replaced by a $\mathbb{Z...
Untangling Surface Codes: Bridging Braids and Lattice Surgery
Alexandru Paler·Nov 27, 2025
We present a systematic method for translating fault-tolerant quantum circuits between their braiding and lattice surgery (LS) representations within the surface code. Our approach employs the ZX calculus to establish an equivalence between these two...

Yang Peng, Rui-Shan Li, Yan-Jue Lv +1 more·Nov 27, 2025
The active manipulation of topologically protected states represents a pivotal frontier for quantum technologies, offering a unique confluence of topological robustness and precise quantum control. We propose an adiabatic pumping scheme for the long-...
Holographically Emergent Gauge Theory in Symmetric Quantum Circuits
Akash Vijay, Jong Yeon Lee·Nov 26, 2025
We develop a novel holographic framework for mixed-state phases in random quantum circuits, both unitary and non-unitary, with a global symmetry $G$. Viewing the circuit as a tensor network, we decompose it into two parts: a symmetric layer, which de...
