Entangled “Frankenstein” Photons Entangled "Frankenstein" Photons David R. Schneider (David@DrChinese.com) Abstract: The H> and V> outputs of a Polarizing Beam Splitter can be combined to restore the original input superposition state, as long as no knowledge is obtained regarding the path taken through the PBS. Using this principle, it should be possible to create entangled photons from the identical H> and V> components of different polarization entangled photons. These "Frankenstein" photons will also be polarization entangled and should violate a Bell Inequality. ----------------------------------------------------- Here is a link to the paper, which has too many formulae/diagrams to properly include within this post: http://www.drchinese.com/David/EntangledFrankensteinPhotonsA.pdf It is attached as well. Also attached are the key diagrams which give a pretty good idea of the proposed setup. Author comments for submission per IR guidelines: This work does not go against any existing experiment or generally accepted result. It extends existing application of theory with a proposed experiment to confirm or deny the central hypothesis. The hypothesis itself is an extension of an idea proposed by J.H. Eberly . Full references are below. This work is relevant because it addresses yet another aspect of local realism: is the wave function fundamental? The local realistic side would assert that a probability amplitude is not real, but is an artifact of our lack of knowledge of the quantum world. And yet, experiment after experiment demonstrates unusual and counterintuitive elements: Entanglement of photons that have never interacted, hyperentanglement, etc. In fact, the very existence of entanglement (and superpositions) is a counter-example to local realism. This paper proposes that it is possible to create photons (Chris and Dale) which are themselves superpositions of 2 other photons (Alice and Bob) - and yet are properly neither alone. Such superposition is demonstrated by observation of a Bell state, signaling entanglement. The novel element is the combination of wave state of different photons. As far as I am aware, there is little in the literature regarding the interaction of wave components from different photons. ------------------------------------------------------ References: 1. G.
