Now at #QuPa (at @InHenriPoincare), Giacomo Mauro D’Ariano from @unipv on “re-establiching Causality”
#LTQI

@InHenriPoincare @unipv Giacomo Mauro D’Ariano: Causality is a theorem of quantum theory. The theorem is actually trivial (in terms of circuits) in the OPT formulation of quantum mechanics.
“The probability of preparation is independent of the choice of observation”

@InHenriPoincare @unipv Giacomo Mauro D’Ariano’s opinion paper [sic] is available at arxiv:1804.10810 arxiv.org/abs/1804.10810

@InHenriPoincare @unipv Griacomo Mauro D‘Ariano: Quantum causality is the same as Einstein’s. A classical causal network has causality, a quantum causal network gives back Lorentz transformations

Giacomo Mauro D’Ariano: Actually, one finds a distrotion of Lorentz group, which is perfectly equivalent to Lorentz group in the relevant k≫1 limit ( arXiv:1503.01017 arxiv.org/abs/1503.01017 / PRA 94 042120 doi.org/10.1103/PhysRe… )
