Thermal Light Resolves the Hidden Pair
Photon-number correlations narrowed temporal features 11.8-fold and spatial features 5.1-fold in a proof-of-principle experiment.
Summary
Photon-number correlations narrowed temporal features 11.8-fold and spatial features 5.1-fold in a proof-of-principle experiment.
The experiment splits classical thermal light in a Hanbury Brown-Twiss interferometer and resolves photon counts in both arms. Correlating multiphoton subsystems produces a peak or dip whose width can be tuned with average photon number. The authors report 11.8-fold temporal and 5.1-fold spatial resolution enhancements; a double pinhole unresolved by ordinary ghost imaging becomes distinguishable in a two-photon-versus-zero-photon correlation. The six-page preprint presents a proof of principle, not a general-purpose imaging system.
