- hugh3 15y agoHe can't. It doesn't work that way. I'm not sure what you think the reciever would be able to detect if the sender did that, but there's no detectable signal. If you provide a more detailed picture of what you're envisaging then I can probably explain exactly what's wrong with it, but please read and understand http://en.wikipedia.org/wiki/Bell_inequality http://en.wikipedia.org/wiki/Bell_inequality and http://en.wikipedia.org/wiki/Bloch_sphere http://en.wikipedia.org/wiki/Bloch_sphere along with any subordinate articles you'd need in order to understand these two, before proceeding.
