In standard quantum mechanics, the effects of write errors (imperfect Bell measurements) and guide errors (classical channel noise) on the final fidelity of quantum teleportation are considered to be nonlinearly coupled and inseparable. Based on the Instantaneous Teleportation Cosmos (ITC) theory, this paper proposes a testable prediction: write and guide errors are physically independent within the ITC framework. Furthermore, if the output quantum state is well approximated by a depolarized state, then the final fidelity satisfies the product relation in terms of information proportion: (2Ffinal−1)=(2Fwrite−1)×(2Fguide−1). We design an experimental scheme using a spontaneous parametric down-conversion (SPDC) entangled photon source, independently controlling the write fidelity (0.80–0.95) and the guide fidelity (0.80–1.00), and employ a chi‑square goodness‑of‑fit test to discriminate between the two frameworks at the 7σ significance level. Regardless of whether the experimental result supports or falsifies the product relation, it will provide critical constraints on the error mechanism of quantum teleportation: if the prediction holds, it would be consistent with the physical independence of the write and guide processes as posited by the ITC framework, motivating further theoretical scrutiny of both ITC and standard quantum mechanical noise models; if falsified, it would demonstrate a deviation from the strict product relation, thereby challenging the independence assumption of ITC and providing new empirical input for refining noise models in quantum teleportation. The proposed experiment is based on existing technology, requires a total of 200,000 events, and can be completed in about 55 hours of data acquisition, offering clear scientific value and feasibility.
