Package: qtsa Title: Quantum Time Series Analysis: Drift, Noise Spectroscopy and Calibration Forecasting Version: 0.1.1 Author: Leila Marvian Mashhad [aut, cre] Maintainer: Leila Marvian Mashhad Authors@R: person("Leila", "Marvian Mashhad", email = "leila.marveian@gmail.com", role = c("aut", "cre")) Description: Tools for exploratory statistical analysis of quantum-hardware calibration time series. The package provides simulators for random telegraph noise (RTN), power-law noise, and Ornstein-Uhlenbeck dephasing; Welch and sine-multitaper power spectral density estimators; a lightweight two-state hidden Markov model for switching signals; cumulative sum (CUSUM) and binary-segmentation diagnostics for calibration drift; residual-quantile interval forecasts; and filter-function calculations for illustrative coherence curves. The package includes a reproducible generator of simulated superconducting-qubit calibration records; it does not retrieve authenticated live provider data. Methodological background is provided by Welch (1967) , Thomson (1982) , Rabiner (1989) , Page (1954) , Paladino et al. (2014) , and Cywinski et al. (2008) .
