Reply to Critique by Ghirardi of Entanglement Communication Scheme by Cornwall

Authors: Remi Cornwall

This short letter is a response to an analysis by Ghirardi of a supposed flaw in a communication scheme involving entangled state collapse. We find his analysis entirely correct but missing the point, which is subtle, the no communication theorem merely expresses the truth of the locality of quantum state information on measurement but surprisingly says nothing about the particle being present or not by dint of the communication scheme itself. Ghirardi’s analysis using the density matrix approach does not deal correctly with the analysis of superposition in the interferometer and as such, doesn’t even correctly replicate the case for non-entanglement, as did the state vector method used by Cornwall.

Comments: 4 Pages. Proof and apparatus showing No-communication Theorem is wrong.
