An attacker can inject bright light into the quantum channel to trick the tracking sensors (e.g., power monitors). By manipulating the feedback loop, an attacker might force the system to open shutters or change polarization states to facilitate an intercept. Optical isolators and spectral filters are required at the tracking sensor inputs.
