Supporting files for "Exact optimal single-shot discrimination of a relaxing qubit under continuous measurement

Exact optimal readout of a relaxing qubit: selected code and data. - src/exact_theory.py : closed-form expressions of the paper: the infinite-window optimal error, Eq. (9), the strong-measurement expansion, and the finite-window bound, Eq. (19). - data/windows.csv : discrete-time likelihood-ratio simulation of the optimal error for 778 finite-window configurations (2×10^4 samples each, with standard errors and per-configuration seeds). Columns ending in _v1 come from an earlier estimator and are not used in the paper. - src/engine_compare.py → data/engine_compare.json : comparison of these simulations with Eq. (9), the bound Eq. (19), and the heuristic Eq. (21) (Fig. 4(a)). - data/finite_window_examples.json : finite-window examples of Fig. 4(b). Requirements: Python 3, numpy, scipy, mpmath.
