Thermal_Diagnostic_System_by_Quantum_Tomography

This version develops a rigorous experimental framework for spatial thermal diagnostics
using superconducting qubits as distributed sensing elements. The central methodological
change relative to a simple frequency-to-temperature conversion is the introduction of an
explicit measurement model separating thermal and non-thermal contributions to the observed
qubit-frequency shift.

Only after characterization of these contributions is a temperature estimate formed. The
local thermal response is represented by a calibrated coefficient

with explicit uncertainty and possible nonlinear correction.
The spatial inverse problem is formulated through a response matrix, a point-spread
function (PSF), and regularized reconstruction. Spatial resolution is therefore not identified
simply with sensor spacing.
The protocol introduces independent reference thermometry, blocked test data, blind lo-
calized thermal perturbations, cross-validation, uncertainty propagation, hierarchical analysis
across cooldowns, and predefined falsification criteria. The primary endpoint is the inde-
pendently evaluated reconstruction error of the thermal field. Secondary endpoints include
effective spatial resolution, temperature resolution, localized perturbation detection, calibration
stability, and cross-cooldown reproducibility.
The proposal remains exploratory and falsifiable. It does not claim experimental validation,
universal thermometry, or superiority over conventional thermal sensors.
