RT Journal Article T1 Coherence versus interferometric resolution A1 Luis Aina, Alfredo AB We examine the relation between second-order coherence and resolution in the interferometric detection of phase shifts. While for classical thermal light resolution and second-order coherence are synonymous, we show that for quantum light beams reaching optimum precision second-order coherence and resolution become antithetical.
