Is Faster-Than-Light Communication Possible?

Abstract. It is shown here using elementary quantum mechanics that a method exists for transmitting signals faster than the speed of light. The method relies on measurement of the uncertainty of momentum for one photon of each pair. The uncertainty is affected by whether momentum or position is measured for the partners, due to Heisenberg’s uncertainty principle. For each pair the effect is instantaneous; so if the measurement of momentum uncertainty, done on one end, is distant from the momentum/position measurement switching done on the other end, then such behavior can be utilized for faster-than-light signaling.
