Union-find decoder for surface code achieves finite threshold under circuit-level stochastic errors with quasi-polylog parallel runtime bound.
A new framework maps microscopic inputs to universal properties of generic symmetry-enriched TQSLs and establishes a bijective crystalline equivalence principle between lattice-plus-internal and internal-only symmetry data.
The paper introduces a form-domain criterion and proves a sufficiency theorem that identifies which gapped observer sectors remain semiclassically admissible in Euclidean de Sitter gravity on the sphere.
Genuine multi-entropy in the toric code reduces to topological entanglement entropy for stabilizer states at low replica index but captures independent topological data at n=4 and for non-stabilizer states.
Majorana fermion motion serves as a primitive for braiding-based logical gates in stabilizer codes, enabling denser packing and numerical outperformance of lattice surgery for 2-qubit Clifford gates under near-term noise.
InAs-Pb hybrid nanowire tetron achieves ~20 s parity switching time with h/2e-periodic bimodal capacitance shifts, using a new rf technique to resolve wire-end states at μeV precision.
A mapping of the Jaynes-Cummings-Hubbard model onto the spin-1/2 Quantum Link Model via tuned polaritonic resonances in cavity arrays enables analog simulation of U(1) LGT dynamics with matter, verified by exact diagonalization.
Deterministic QITE with a Gauss-law-reduced Pauli pool reproduces DMRG ground-state energies of (2+1)-D pure Z2 lattice gauge theory to within 0.1% for ladders of up to 32 qubits and coupling λ ∈ [0.5, 5].
In disordered topological superconductor antidot vortices, Majorana zero mode probability density variance is twice that of CdGM states because MZM wave functions are real while CdGM ones are complex.
Derives explicit non-perturbative renormalization relations between bare parameters and physical observables in waveguide QED to handle IR and UV cutoffs in simulations.
Benchmarks gradient-ascent algorithms for constrained free energy minimization on quantum Heisenberg models and stabilizer codes, with applications to thermal state design and fixed-temperature quantum encoding.
Decoherence on abelian topological order is modeled as a temporal defect in double TQFT driving boundary anyon condensation transitions classified by Lagrangian subgroups of the doubled order.
New algorithms based on Dicke states enable qubit-efficient quantum simulations of collective neutrino oscillations with demonstrated performance on classical and quantum hardware.
Real observers remove the de Sitter imaginary phase only if their fluctuations share the conformal factor's negative modes; metric-independent sectors factorize and preserve the phase.
