Automorphism in Gauge Theories: Higher Symmetries and Transversal Non-Clifford Logical Gates
Po-Shen Hsin, Ryohei Kobayashi·Nov 19, 2025
Gauge theories are important descriptions for many physical phenomena and systems in quantum computation. Automorphism of gauge group naturally gives global symmetries of gauge theories. In this work we study such symmetries in gauge theories induced...
Parity anomalies in 2+1-dimensional Aharonov-Bohm type configurations
Harun Basmaci, Hasan Ozgur Cildiroglu·Nov 19, 2025
We demonstrate that Dirac fermions in 2+1 dimensions, coupled to Abelian gauge fields in multiply-connected regions, exhibit a parity anomaly that directly manifests as Aharonov-Bohm (AB) type topological phases. Using the Fujikawa method, we show th...
Topological Quantum Transducers in a Hybrid Rydberg Atom System
Pei-Yao Song, Jin-Lei Wu, Weibin Li +1 more·Nov 19, 2025
We propose a topological transport platform for microwave-to-optical conversion at the single-photon level in a Rydberg atom-cavity setting. This setting leverages a hybrid dual-mode Jaynes-Cummings (JC) configuration, where a microwave resonator cou...
Pure gapped ground states of spin chains are short-range entangled
Wojciech De Roeck, Martin Fraas, Bruno de O. Carvalho·Nov 18, 2025
We consider spin chains with a finite range Hamiltonian. For reasons of simplicity, the chain is taken to be infinitely long. A ground state is said to be a unique gapped ground state if its GNS Hamiltonian has a unique ground state, separated by a g...
Current Switching of Topological Spin Chirality in the van der Waals Antiferromagnet Co1/3TaS2
Kai-Xuan Zhang, Seungbok Lee, Woonghee Cho +1 more·Nov 18, 2025
Magnetic topology is central to modern quantum magnet, where spin chirality governs exotic spin winding, real-space Berry phase, and topological Hall effect. A key unresolved challenge is how to electrically switch topological spin chirality and its ...
Canonical quantization for Equilibrium Thermodynamics
Luis F. Santos, Victor Hugo M. Ramos, Danilo Cius +2 more·Nov 18, 2025
We formulate a canonical quantization of Equilibrium Thermodynamics by applying Dirac's theory of constrained systems. Thermodynamic variables are treated as conjugate pairs of coordinates and momenta, allowing extensive and intensive quantities to b...
Screw-dislocation-engineered quantum dot: geometry-tunable nonlinear optics, orbital qubit addressability, and torsion metrology
Edilberto O. Silva·Nov 17, 2025
We study a single electron confined in a uniform-torsion medium, a continuum model of a screw dislocation density, in a perpendicular magnetic field, and in the presence of an Aharonov--Bohm flux. Torsion alone produces radial confinement without any...
Non-invertible defects in generalized Ising models via strange correlator
Aswin Parayil Mana, Yaman Sanghavi·Nov 17, 2025
Defects associated with non-invertible symmetries have attracted significant attention in recent years. Among them, Kramers-Wannier (KW) duality defects have been investigated in both classical statistical systems and quantum Hamiltonian models. Aase...
Quantum Metamorphosis: Programmable Emergence and the Breakdown of Bulk-Edge Dichotomy in Multiscale Systems
Mahmoud Jalali Mehrabad, Alireza Parhizkar, Lida Xu +6 more·Nov 17, 2025
Multiscale synergy -- the interplay of a system's distinct characteristic length, time, and energy scales -- is becoming a unifying thread across many contemporary branches of science. Ranging from moiré and super-moiré materials and cold atoms to DN...
Skeleton of isometric Tensor Network States for Abelian String-Net Models
Julian Boesl, Yu-Jie Liu, Frank Pollmann +1 more·Nov 17, 2025
We construct parametrized isometric tensor network states -- referred to as skeletons -- that allow us to explore phases of abelian topological order and can be efficiently implemented on quantum processors. We obtain stable finite correlation length...
Simultaneous variances of Pauli strings, weighted independence numbers, and a new kind of perfection of graphs
Zhen-Peng Xu, Jie Wang, Qi Ye +3 more·Nov 17, 2025
A set of Pauli stings is well characterized by the graph that encodes its commutatitivity structure, i.e., by its frustration graph. This graph provides a natural interface between graph theory and quantum information, which we explore in this work. ...
High-Fidelity Universal Quantum Gate Compilation for Non-semisimple Ising Anyons via Genetic Algorithm-Optimized Solovay-Kitaev Decomposition
Jiangwei Long, Zihui Liu, Yizhi Li +2 more·Nov 17, 2025
We present a systematic numerical construction of a universal quantum gate set for topological quantum computation based on the non-semisimple Ising anyons model. By employing a Genetic Algorithm-enhanced Solovay-Kitaev Algorithm (GA-enhanced SKA), w...
Topological enhancement of a PT-symmetric Su-Schrieffer-Heeger quantum battery
A-Long Zhou, Ya-Wen Xiao, Nuo Xu +5 more·Nov 17, 2025
We investigate a non-Hermitian quantum battery based on the Su-Schrieffer-Heeger (SSH) lattice, charged through a PT-symmetric protocol that alternates gain and loss between the two sublattices. The interplay between lattice topology and non-Hermitic...
Topological Phases in Non-Hermitian Nonlinear-Eigenvalue Systems
Yu-Peng Ma, Ming-Jian Gao, Jun-Hong An·Nov 17, 2025
The discovery of topological phases has ushered in a new era of condensed matter physics and revealed a variety of natural and artificial materials. They obey the bulk-boundary correspondence (BBC), which guarantees the emergence of boundary states w...
Vortex states and entanglement properties in multiphoton pair production
Hong-Hao Fan, Lie-Juan Li, Zhi-Hang Yao +3 more·Nov 16, 2025
We investigate the multiphoton pair production in circularly polarized field via two level model. There appears obvious discrete ring structures in the momentum distribution of the created particles, in which the ring radius is mainly controlled by t...
Skyrmionic qubits stabilized by Dzyaloshinskii-Moriya interaction as platforms for qubits and quantum gates
Doru Sticlet, Romulus Tetean, Coriolan Tiusan·Nov 15, 2025
Quantum computation departs from the classical paradigm of deterministic, bit-based processing by exploiting inherently quantum phenomena such as superposition and entanglement. We propose a framework for qubit realization based on skyrmionic states ...
Photonic spin Hall effect in $\mathcal{PT}$-symmetric non-Hermitian cavity magnomechanics
Shah Fahad, Muzamil Shah, Gao Xianlong·Nov 15, 2025
Non-Hermitian cavity magnomechanics (CMM), which incorporates the magnon-photon and magnon-phonon interactions simultaneously, enables rich physical phenomena, including exceptional-point-enhanced sensing, and offers pathways toward topological trans...
Subradiant Decay in 2D and 3D Atomic Arrays
Nicola Piovella, Romain Bachelard·Nov 14, 2025
Subradiance is a phenomenon where coupled emitters radiate light at a slower rate than independent ones. While its observation was first reported in disordered cold atom clouds, ordered subwavelength arrays of emitters have emerged as promising platf...

Wanda P. Duss, Askar Iliasov, Tomáš Bzdušek·Nov 14, 2025
We derive the full spectrum of decorated Cayley trees that constitute tree analogs of selected two-dimensional Euclidean lattices; namely of the Lieb, the double Lieb, the kagome, and the star lattice. The common feature of these Euclidean lattices i...
Magnetic flux and its topological effects in Aharonov-Bohm effect
Manvendra Somvanshi, D. Jaffino Stargen·Nov 14, 2025
The Aharonov-Bohm effect is a physical phenomenon in which the quantum state of a charged particle acquires a phase shift that is directly proportional to the magnetic flux, $Φ$, due to a (classical) magnetic field, ${\mathbf B}$, which is confined i...
