Abstract
Recent results on causality in noncommutative space-time are reviewed. We study, in particular,
quantum causal structures in 1+1 dimensional kappa Minkowski space-time. This later is described
by a twisted Lorentzian Spectral Triple build with a twisted set of derivatives. Investigation of
causality provides a quantum constraint, which is a quantum analog of the speed light limits.
