A coherent two-level system residing in the tunable coupler is shown to couple simultaneously to two distant qubits, producing tunable non-local non-Markovian decoherence and a 1/f noise spectrum spanning ten orders of magnitude.
A new Sparse Stabilizer Tensor cost function enables hyper-optimized contraction schedules for Quantum LEGO WEP calculations, delivering orders-of-magnitude improvements over dense tensor baselines for stabilizer codes.
Tricycle codes generalize bicycle codes to three homological dimensions, enabling constant-depth CCZ circuits and single-shot magic state generation with circuit-level thresholds above 0.5% and low error rates at block lengths of 50-100 qubits.
HAL heuristic produces explicit layouts for bivariate bicycle, tile, radial, and Tanner qLDPC codes on multilayer superconducting hardware, demonstrating that open-boundary designs reduce hardware demands with only moderate loss in logical efficiency.
Cyclic control via parameter-space expansion restores controllability in fast CZ gates despite short-timescale distortions, cutting average coherent error from 0.27% to 0.12% in superconducting qubit experiments without extending gate duration.
Triage is an adaptive parallel window decoding scheduler that reduces average logical error rates by 52.6% compared to standard temporal parallelism while keeping stalls low under scarce classical resources.
A programmable 2D toric oscillator network enables efficient routing for bivariate bicycle LDPC codes, reducing long-range couplers to O(sqrt(n)) and achieving 3.06% logical error rate per cycle in simulations for the [[18,4,4]] code.
O3LS reduces space overhead by up to 46.7% and time overhead by up to 36% in lattice surgery while suppressing logical error rates by up to an order of magnitude compared with prior layout and scheduling approaches.
Geometry choices in bivariate-bicycle qLDPC syndrome extraction determine leading correlated error structure via weighted exposure, which correlates strongly with logical error rates and is reduced by biplanar layouts.
An exact positive-probability decomposition of thermal relaxation noise into Clifford gates and resets exists for T2 ≤ T1, with a negativity-free approximation that outperforms Pauli twirling for T2 > T1.
Canopus unifies qubit mapping and routing across quantum ISAs by modeling synthesis costs via canonical two-qubit gate forms, achieving 15-35% lower routing overhead than prior methods on varied backends and topologies.
A review summarizing spin qubit platforms, long-range coupling methods, and a proposal for topological linking toward scalable quantum information processing.
