We present a density-matrix simulation framework for quantum teleportation that integrates a comprehensive set of physically motivated noise channels calibrated to contemporary superconducting processors. Departing from deferred-measurement simplifications, the simulator explicitly tracks measurement branches of the Bell measurement and models realistic effects, including readout misassignment, coherent control errors, leakage, crosstalk, and low-frequency dephasing. The framework produces an end-to-end error budget and is validated against experimental executions, with extensive statistical checks (bootstrap confidence intervals, hypothesis tests, and goodness-of-fit analysis) demonstrating close agreement between predicted and measured state-transfer behavior. Our analysis highlights readout misassignment as the dominant fidelity limiter in the measurement-based protocol and shows that targeted readout mitigation provides higher leverage than equivalent improvements in coherence alone. The implementation is extensible to multi-qubit and networked teleportation protocols and serves as a practical tool for forecasting teleportation performance on near-term quantum hardware.
