Proposed experiment to test photon anticorrelation with quantitatively controllable source emission rate

We describe a proposed experiment that will establish whether or not the op tical field is quantized. We argue that previous attempts to establish this have not been conclusive. Quantum optics and Maxwell electrodynamics predi ct different outcomes for the experiment which is an improved version of th at performed by Brown and Twiss in 1956 (Nature 177 27-9). The Brown-Twiss experiment did not distinguish between the two theories because its source was classical. In the proposed experiment, a weak light signal is achieved without selective deletion, and it can be either Poissonian or sub-Poissoni an.
