Suppressing Coherent Two-Qubit Errors via Dynamical Decoupling

2021 · Physical Review Applied

Scalable quantum information processing requires the ability to tune multiqubit interactions. This makes the precise manipulation of quantum states particularly difficult for multiqubit interactions because tunability unavoidably introduces sensitivity to fluctuations in the tuning parameters, …

Neural network based time-resolved state tomography of superconducting qubits

2023 · arXiv (Cornell University)

Superconducting qubits have emerged as a premier platform for large-scale quantum computation, yet the fidelity of state readout is often hindered by random noise and crosstalk, especially in multi-qubit systems. While neural networks trained on …
