Classical codes plus SAT search yield no-go theorems limiting error detection in sub-8-qubit distillation and new minimal-qubit protocols for T-to-T (distances 4-5 on 10-11 qubits) and T-to-CCZ (distances 3-4 on 9-10 qubits).
Quantum coherences bind to hydrodynamic voids forming polaron-like objects, parametrically enhancing lifetimes and producing subdiffusive Green's functions in charge-conserving dynamics.
For PEPS with strong injectivity above a threshold, belief propagation finds fixed points efficiently and cluster-corrected BP approximates observables to 1/poly(N) error in poly(N) time, with local perturbations affecting the fixed point only locally.
Cryogenic shock exfoliation yields large rhombohedral graphene devices over 1300 square micrometers with 90% fabrication yield, mean free path exceeding 200 micrometers, and signatures of electron hydrodynamics.
Alterelectrics exhibit quadrupolar piezoelectricity, hyperbolic wave dispersion, and surface-dependent anisotropic electronic transport as an electric analog to altermagnets.
Genuine quantum scars survive in Floquet many-body systems with additional drive-induced scars and a stability diagram explained by classical Lyapunov exponents.
For PEPS states with loop-decay, BP with cluster corrections approximates local observables exponentially accurately, and loop-decay necessarily implies exponential decay of connected correlations, ruling out BP at critical points.
Engineered disorder drives a photonic lattice into a topological Anderson insulator regime that produces emergent chiral edge states for boundary-selective, ultranarrow lasing with enhanced robustness.
Shaping the pump in a honeycomb photonic-crystal laser creates a smooth potential that traps lasing states with reconfigurable real-space polarization singularities pinned to envelope critical points, while the momentum-space vortex at Gamma remains fixed.
Averaging symmetric Z_N quantum circuits over random noise produces a noisy surface code whose logical information is protected against symmetric errors up to a threshold, with charge-sharpening transitions coinciding with bulk confinement transitions that differ for N≤4 versus N>4.
Symmetry classification of measurement-inclusive fermionic dynamics with equivalence between many-body and single-particle schemes, plus post-selection-free adaptive circuits for topological states in four classes.
A sample-optimal quantum state tomography algorithm that is memory-efficient by using unitary Schur sampling with streaming access to samples.
Thousands of foundry-fabricated quantum-dot spin-photon interfaces demonstrate state-of-the-art efficiency, stable near-unity purity, seven-partite entanglement, and cross-source indistinguishability.
Derives improved mode-independent sample complexity bounds O(η log η) for fermionic classical shadows on particle-preserving operators and Slater determinant overlaps.
Experimental observation of nonlinear dependence of ion loss rate on spin polarization in Ba+ immersed in two-component Li Fermi gas, consistent with antisymmetrization restricting recombination channels.
Proposes relative-entropy-based measures to diagnose chirality in mixed-state topological phases after showing pure-state diagnostics are unreliable.
Broadband laser pulses enhance two-plasmon decay instability and hot electron generation via stochastic intensity spikes, as identified in experiments and particle-in-cell simulations.
Analytical derivation shows mutual relations between density, magnetic, and pairing susceptibilities in the Hubbard model, revealing a degeneracy between d-wave pairing and d-density wave instabilities near the metal-insulator transition that is lifted by frustration.
Quasiprobability models in Bayesian networks generalize to produce all non-signalling correlations for a broad class of networks and conjecturally recover the nested Markov model.
Simulations show update mechanisms decide coexistence versus dominance of upstream and downstream reciprocators, with a robust optimal network degree maximizing upstream reciprocity across conditions.
Derives exact propagator via generating functions for age-dependent switching particles and reports marginal CLT breakdown with Var(x_T) scaling as T²/log T at a=1.
Quenching the hopping term in the strong-coupling half-filled Hubbard model creates a prethermal state with effective temperature reduced by (t_final/t_initial)^2 for doublon-conserving operators, persisting exponentially long in (U/t)^2.
Quantum group symmetry enables superdiffusive hydrodynamic tails for transverse spin operators in chaotic XXZ-like models despite lacking local quantum group charges.
