Estimating and decoding coherent errors of QEC experiments with detector error models

Evangelia Takou, Kenneth R. Brown·Oct 27, 2025

Decoders of quantum error correction (QEC) experiments make decisions based on detected errors and the expected rates of error events, which together comprise a detector error model. Here we show that the syndrome history of QEC experiments is suffic...

Effect of Stochastic Charge Noise in Si/SiGe Quantum-Dot Spin Qubits

Wei-en Chiu, Chia-Hsien Huang, Yi-Hsien Wu +1 more·Oct 25, 2025

In Si/SiGe quantum dots, the decoherence behavior of spin qubits usually comes from the non-Markovian effect of the charge noise. To improve the performance of using the coherent noise models in the decoherence simulation and tomography analysis, her...

Boundaries of Acceptable Defectiveness: Redefining Surface Code Robustness under Heterogeneous Noise

Jacob S. Palmer, Kaitlin N. Smith·Oct 24, 2025

A variety of past research on superconducting qubits shows that these devices exhibit considerable variation and thus cannot be accurately depicted by a uniform noise model. To combat this often unrealistic picture of homogeneous noise in quantum pro...

Suppressing excitations using quantum-Brachistochrone and nearest-neighbour interactions

S John Sharon Sandeep, Dibyajyoti Sahu, Suhas Gangadharaiah·Oct 24, 2025

We examine excitation suppression in the transverse-field Ising model (TFIM), where finite-time drive across a quantum critical point is assisted by the presence of a time-dependent coupling parameter. While conventional counterdiabatic protocols are...
