A low-intensity double-slit experiment was first performed by G. I. Taylor in 1909, by reducing the level of incident light until photon emission/absorption events were mostly non overlapping.
G. I. Taylor realizou por primeira vez o experimento da dobre fenda de baixa intensidade en 1909, ao reducir o nivel de luz incidente ata que a maioría dos eventos de emisión / absorción de fotóns non se superpoñen.
