Abstract: G60.00282 : The Essence of Delayed Choice Entanglement Elimination
One can tie a delayed choice on one of two entangled particles (particle 1) before particle detections to the presence of entanglement or absence of entanglement to differentially affect the other particle (particle 2). This effect on particle 2 can result in the development of distinct types of distributions of particle 2 that exhibit either the absence or presence of interference. The foregoing is the essence of delayed choice entanglement elimination. The particular distribution obtained for particle 2 depends on making the same choice on particle 1 over a number of runs. If over a number of runs the choice on particle 1 is to preserve entanglement, then the relevant distribution of particle 2 will not show interference (instead the one broad hump demonstrating which-way information). If over a number of runs the choice on particle 1 is to eliminate entanglement, then the relevant distribution of particle 2 will show interference. No correlations are needed between the measurements on the paired particles to develop either of the two possible distributions of particle 2. Delayed choice entanglement elimination can be used to develop a non-trivial non-local quantum communication system.
