Zero Mode Operators and Charge-Conjugation Defects in Non-Abelian Fractional Quantum Hall-Superconductor Heterostructures
We study zero modes bound to charge-conjugation defects in fractional quantum Hall-superconductor (FQH-SC) heterostructures built from Abelian and non-Abelian FQH states.Two superconducting pairing models with a Kitaev spin-liquid glue: microscopic kernel and parity alternation on odd-fold bond stars
We construct two superconducting pairing models on doped Kitaev honeycomb, whose microscopic kernels are derived rather than assumed.Interferometric braiding of non-Abelian anyons
The manipulation of non-Abelian anyons is a foundational ingredient for topological quantum computing and underlies topologically protected quantum memories.A Practical Introduction to VQE: Methods, Challenges, and Applications in Physics and Chemistry
The Variational Quantum Eigensolver (VQE) has become a central hybrid quantum-classical method for addressing electronic structure and materials science problems on near-term quantum hardware.Interacting quantum criticality with U(1) symmetry breaking in 1+1 dimensions
The Hohenberg-Mermin-Wagner theorem motivates the expectation that continuous symmetries remain unbroken in one-dimensional quantum ground states.Climbing the Fusion Tree: Center Ordering and Decoding Hierarchy in Non-Abelian Mixed States
We develop an operational approach to strong-to-weak spontaneous symmetry breaking (sw-SSB) of a non-Abelian symmetry group G. We formulate it as the decoding task of distinguishing two strongly…Engineering logical gates with irrep surface codes
Fault-tolerant quantum computation typically relies on a fixed set of logical primitives, while realizing other desired operations can require substantial resources.Rewire and reset are all you need: Minimal resources for manipulating non-Abelions
Braiding and fusing anyons are fundamental to topological quantum computation, yet existing circuit protocols often employ ancillas and measurements.Chiral Parafermions in Floquet $\mathbb{Z}_N$ Topological Order
Floquet topological order (FTO) extends topology beyond equilibrium, giving rise to phenomena, such as the dynamical transmutation of anyons.Connectivity Controls Variational Accessibility in Symmetry-Preserving Quantum Circuits
Designing expressive quantum circuits for the variational quantum eigensolver (VQE) is a central challenge in simulating interacting many-body systems.Onset of a quantum Fisher-Selke sequence in the transverse-field ANNNI model and its bilayer
We study the transverse-field axial next-nearest-neighbor Ising (ANNNI) model on the square lattice and on a bilayer.Cups and Gates II: Operads, twists, and addressable intra-code gates
In Part I, we introduced a general framework for constructing logical gates in quantum CSS codes from cohomology invariants, focusing on cup products and their generalizations from topological to…Nonlinear quantum multi-spin dynamics without entanglement
We introduce a distinct route for extending classical atomistic spin dynamics into the quantum regime for arbitrary spin $s$, based on a variational product-state \textit{ansatz} that includes both…How to distinguish chaos from integrability using OTOC
The decay of out-of-time-ordered correlators (OTOCs) to a small residual value signals the scrambling of quantum information.State-selective entanglement and point-gap topology in the unidirectional Bose-Hubbard chain
We study the effect of repulsive interactions on skin modes and entanglement in the unidirectional Bose--Hubbard model.Topological phase transition in a symmetric blockade structure
We present a numerical study of a blockade Hamiltonian with a local $\mathbb{Z}_2$ symmetry.Efficient Sampling for Many-Body Fermionic Non-Gaussianity
Fermionic non-Gaussianity is a key resource for universal quantum computation, and its behavior in quantum many-body systems has attracted growing interest.Decohering Kitaev's Sixteenfold Way: A Holographic Approach
We study anyon decoherence in 2D topological order, with the fermion decoherence in Kitaev's sixteenfold way as explicit examples.Exact Recovery for Non-Abelian Surface Codes
We study exact recovery for non-Abelian topological surface codes based on the quantum double $D(G)$ of any finite group $G$.Efficient Block Encoding of Structured Hamiltonians by Separating Where and What
In fault-tolerant block encodings of structured Hamiltonians, the support geometry can set how the non-Clifford cost of SELECT scales with the system size, however many operators act on each support.
