Technology / Re: Can we use physics to detect when people look at security devices?
« on: 11/08/2019 23:13:13 »For simplicity I will call a device that uses the double split experiment to detect if someone has percieved the device a "quantum perception switch" or QPS.What exactly do you suppose this QPS does? If it watches the door of the room, then it detects the person directly, and the double slit setup seems to not even be required. So it is watching only the double-slit setup. Exactly what would distinguish the experiment running with or without an observer? You can win a Nobel prize if you can answer that.
The way I understand the double slit experiment is the observation can be made with the naked eye, so a casual observer would activate it just by looking at it. This should be more efficient then the more processor intensive ways of detecting people. If a device is required to make the observation then the QPS would not work the way I imagine it would.
