A new compilation framework treats quantum channels as first-class objects via ChannelIR and LindFront, achieving up to 99% gate count reduction on Lindbladian benchmarks versus unoptimized and Stinespring baselines.
A randomized linear-time phase-folding algorithm using constant-width bitstring abstraction optimizes T-count in quantum circuits orders of magnitude faster than prior tools while achieving comparable reductions.
Embedding experimental quantum states into high-distance codes enables exponential speedups in fault-tolerant shadow tomography and cubic observable estimation over unencoded adaptive strategies.
KOVAL-Q uses SAT solving to optimize and verify surface-code logical operations with general encodings, finding d-cycle CNOTs and 2d-cycle rotations that reduce FTQC application runtime by about 10 percent.
Cobble is a domain-specific language for quantum block encodings that compiles high-level matrix expressions to optimized circuits using analyses and quantum singular value transformation, achieving 2.6x-25.4x speedups over unoptimized baselines on benchmarks.
Search-based approximate diagonalization followed by analytical inversion yields high-precision multi-qubit Clifford+T circuits with 95% fewer non-Clifford gates on real-algorithm benchmarks.
Lattice-surgery scheduling is mapped to 3D path embedding and solved with look-ahead Dijkstra projection, yielding 3.8x lower execution time on quantum phase estimation benchmarks versus greedy scheduling.
Sparse Mamba Decoder processes only active defects in surface code syndromes using a 13-feature representation and Mamba backbone for O(k) complexity, reporting speedups and accuracy gains over dense decoders.
Stochastic magic-state production in fault-tolerant quantum computing inflates execution time but reduces peak resource demand, allowing stochastic-aware factory allocation to cut space-time volume by up to 27% and factories by up to 30% versus deterministic optima.
Symmetry counting of error configurations yields closed-form approximations for logical error rates in surface codes.
Orkan simulates quantum operations on Hermitian operators using a cache-friendly tiled lower-triangle layout, halving memory and achieving 2-4x speedups over Qiskit Aer, QuEST, and Qulacs.
Randomized sparse-QSVT reduces gate counts by up to 10x for inhomogeneous many-term Hamiltonians at moderate error (around 10^{-3}), but deterministic QSVT becomes cheaper for higher precision.
Reordering database addresses before ESOP minimization produces smaller QROM circuits for Grover oracles, with simulated annealing yielding roughly 30% size reduction over fixed ordering for small N.
A space-efficient quantum ECDLP algorithm uses 5n + 4⌊log₂n⌋ + O(1) logical qubits and O(n³) Toffoli gates, lowering the 256-bit estimate from 2124 to 1333 qubits.
Multiple-braiding sequences with multiplicities up to nine in SU(2)_k anyon models enable approximation of a universal gate set {H, T, CNOT} for k>2, k≠4, with numerical evidence from genetic algorithms.
Local syndrome-based preprocessing accelerates BP decoders for quantum LDPC codes, delivering up to 10x speedup on the [[144,12,12]] code while maintaining or improving logical error rates.
Empirical study of real NISQ order-finding data identifies dominant verified mass fraction as the strongest predictor of whether standard post-processing recovers the true order.

The work identifies a fidelity crossover separating distillation-dominated and no-distillation regimes for remote entanglement in lattice surgery, with up to 100x or >50% resource savings depending on the side of the threshold.
Three architectural types for fault-tolerant distributed quantum computing exhibit distinct scaling of Bell-pair consumption and generation attempts with code distance in planar surface and toric codes.
Concatenating surface codes with quantum Hamming codes achieves high error thresholds up to the surface code limit and suppresses logical errors more effectively than surface codes with comparable overhead for intermediate-scale quantum memories.
A two-level decoder scheduling framework reduces classical processing requirements for quantum error correction by 10-40% on fault-tolerant benchmarks by managing bursty workloads as shared resources.
Raising the atomic-layer deposition temperature of Al2O3 and using HfO2 or poly-Si gates in SiMOS devices correlates with higher mobility and lower charge noise, yielding more stable quantum dots.
