Remote-Sensing Quantum Hyperspace by Entangled Photon Interferometry

Click For Summary
SUMMARY

The discussion centers on the paper titled "Remote-Sensing Quantum Hyperspace by Entangled Photon Interferometry," which revisits the Delayed Choice Quantum Eraser Experiment originally conducted by Yoon-Ho Kim and others. The authors assert that hidden topological properties within the experiment allow for the potential extraction of real-time quantum information from hypersurfaces beyond the future light cone, without violating causality. This claim challenges previous conclusions regarding Faster-Than-Light (FTL) information extraction and suggests new avenues for quantum radar applications.

Abstract

Even though ideas of extracting future-related, or Faster-Than-Light (FTL) information from hyperspace using quantum entanglement have generally been refuted in the last ten years, in this paper we show that the original '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, still features hidden topological properties that may have been overlooked by previous analysis, and which 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 such properties can be removed, and quantum-level information from certain hypersurfaces of past, present or future spacetime may be collected real-time, without resulting in any paradox or violation of causality.

"Quantum property map could be scanned just like background microwave radiation; showing the optically non-observable regions of our universe."

This paper essentially claims it is possible to extract information from hypersurfaces lying outside of your future lightcone (past, present future) by modified delayed-choice quantum eraser experiment.
