Abstract
We experimentally demonstrate that a superconducting nanowire \nsingle-photon detector is deterministically controllable by bright illumination. \nWe found that bright light can temporarily make a large fraction of the \nnanowire length normally conductive, can extend deadtime after a normal \nphoton detection, and can cause a hotspot formation during the deadtime with \na highly nonlinear sensitivity. As a result, although based on different physics, \nthe superconducting detector turns out to be controllable by virtually the same \ntechniques as avalanche photodiode detectors. As demonstrated earlier, when \nsuch detectors are used in a quantum key distribution system, this allows an \neavesdropper to launch a detector control attack to capture the full secret key \nwithout this being revealed by too many errors in the key.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
