Separate and efficient characterization of state-preparation and measurement errors using single-qubit operations
Muhammad Qasim Khan, Leigh M. Norris, Lorenza Viola
In many platforms, errors from state-preparation and measurement (SPAM) dominate over single-qubit gate errors. To inform further hardware improvements and the development of more…

Efficient learning and optimizing non-Gaussian correlated noise in digitally controlled qubit systems
Wenzheng Dong, Yuanlong Wang, Muhammad Qasim Khan
Precise qubit control in the presence of spatio-temporally correlated noise is pivotal for transitioning to fault-tolerant quantum computing. Generically, such noise can also have…

SPAM-Robust Multi-axis Quantum Noise Spectroscopy in Temporally Correlated Environments
Muhammad Qasim Khan, Wenzheng Dong, Leigh M. Norris +1
Characterizing temporally correlated (``non-Markovian'') noise is a key prerequisite for achieving noise-tailored error mitigation and optimal device performance. Quantum noise spe…
