Photonic Hardware Cross Scans

Detector Efficiency Three-Row Scan

Several exact efficiency gates show detected and missed photons as one count ledger. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

Half efficiency clicks six of twelve

The detector receives 12 photons. Efficiency 1/2 gives 6 clicked and 6 missed.

12⋅12=6,6+6=1212\cdot\frac{1}{2}=6,\quad 6+6=12

Two-thirds efficiency clicks eight of twelve

Efficiency 2/3 sends 8 photons to clicked and 4 to missed.

12⋅23=8,8+4=1212\cdot\frac{2}{3}=8,\quad 8+4=12

Three-quarters efficiency clicks nine of twelve

Efficiency 3/4 gives 9 clicked photons and 3 missed photons.
