A system, apparatus and method for controlling the stoppage of a spinning wing of a migratory bird decoy. When power is turned off by a remote controller, a photo eye sensor system identifies when a motor shaft needs to stop spinning so that the dark side of a wing stops facing upward. When the motor shaft is in a correct location, a wing shaft control cylinder is engaged, which locks the motor shaft / wing in the correct position with the dark side (feather) up. When engaged, a pin from the cylinder goes into a motor gear housing, which stops and holds the wing shaft, and therefore the wing, in the correct position.

The invention relates to the technical field of quantum information, in particular to a passive decoy state-based reference system independent quantum key distribution method. A reference frame independent quantum key distribution (RFI-QKD) protocol may still generate a secure key when the reference frame has a slow and unknown drift. In order to solve the potential side information leakage loophole in the active decoy state modulation process, the RFI-QKD protocol based on the passive decoy state is invented. Two beams of weak coherent light are subjected to interference in the beam splitter, and the signal light at the output end is divided into two types of photon number distribution according to the response result of the detector end, so that the risk caused by active modulation of light intensity can be avoided. Considering that single photon avalanche detectors (SPAD) of a transmitting end and a receiving end have inevitable post-pulse effects, a post-pulse compatible analysis model is constructed. A simulation result shows that the method is good in performance in an actual application scene.
