Post-selected enhancement of phase sensitivity in a two-path interferometer
Ryuya Fukuda, Katsuki Tanaka, Masataka Iinuma +1
Post-selected metrology can exceed the standard quantum limit of single photon interference by concentrating all of the available Fisher information in a subset of post-selected ou…

Experimental evidence for the physical delocalization of individual photons in an interferometer
Ryuya Fukuda, Masataka Iinuma, Yuto Matsumoto +1
It is generally assumed that the detection of a single photon as part of an interference pattern erases all possible which-path information. However, recent insights suggest that w…
