Faster Communication Using Probabilistic Swapped-Bell-States Analysis

Abstract: In this article, a procedure called Probabilistic Swapped-Bell-States Analysis (PSBA) is proposed. Using this procedure two communication partners can transmit (binary-encoded) information over large spatial distances. This procedure is unusual insofar as no classical communication channels are used either during or after information encoding. To make this possible, entanglement swapping is used as a transport channel. The encoding of bits is realized by the execution (or non-execution, as the case may be) of entanglement swapping on multiple photon pairs, while decoding is realized by a statistical detection of swapped entanglements. If the PSBA procedure sustains itself against a rebuttal by the scientific community, it would constitute a technical approach for transmitting information faster than light. The PSBA procedure seems to be in harmony with the no-communication theorem, since PSBA does not manipulate (and teleport) specific states from one (entangled) particle to another in order to communicate, but instead uses statistics on entanglement swappings for information encoding.
