Abstract
Section titled āAbstractāUsing a qubit to probe non-Gaussian noise environments is theoretically\nstudied in the context of classical random telegraph processes. Protocols for\ncontrol pulses are developed to effectively scan higher noise correlations,\noffering valuable information on the charge environment of the qubit.\nSpecifically, the noise power spectrum and trispectrum are reconstructed\nsimultaneously for a wide range of qubit-fluctuator coupling strengths,\ndemonstrating the methodās robustness. These protocols are readily testable in\nvarious qubit systems with well-developed quantum control, including quantum\ndot spins, superconducting qubits and NV centers in diamond.\n
