00925njm 22002777a 4500 dc Luis Aina, Alfredo author Peřina, J. author 1996-06-03 Two examples are presented where the photon emission on spontaneous parametric down-conversion is prevented when attempts are made to infer the moment of emission. This inhibition is analyzed in terms of the disturbance caused on the system by the modifications that must be introduced in order to make possible such inference. 0031-9007 10.1103/PhysRevLett.76.4340 https://hdl.handle.net/20.500.14352/59727 http://dx.doi.org/10.1103/PhysRevLett.76.4340 http://journals.aps.org/ Zeno effect in parametric down-conversion
