Decoding back from the future messages?

Remote-Sensing Hyperspace by a modified, Delayed-Choice Quantum Eraser interferometry experiment
Gergely A. Nagy
(Submitted on 11 Jan 2011)
In this paper we show that the 'Delayed Choice Quantum Eraser Experiment', 1st performed by Yoon-Ho Kim, R. Yu, S.P. Kulik, Y.H. Shih, designed by Marlan O. Scully & Druhl in 1982-1999, features various topological properties that may prohibit, by principle, the extraction of future-related or real-time information from the detection of the signal particle on the delayed choice of its entangled idler twin(s). We show that all such properties can be removed, and quantum-level information from certain hypersurfaces of past, present and even future spacetime may be collected real-time, without resulting in any paradox or violation of causality.

Generally these ideas are refuted. I have yet to read this paper and so far I am not aware of a fatal flaw.

I don't understand his sentence:

"We point out, that such phenomenon could also be used to realize non-retrocausal, superluminar (FTL) communication as well."

"non-retrocausal"?
