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…
Characterization of non-classical particle propagation using superpositions of position and momentum
Yuki Senoo, Holger F. Hofmann, Hiroki Yamakami +1
The uncertainty principle suggests a quantitative trade-off between the control of position and the control of momentum in particle propagation. However, a superposition of two sta…
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…
Quantum contextuality of complementary photon polarizations explored by adaptive input state control
Kengo Matsuyama, Ming Ji, Holger F. Hofmann +1
We experimentally investigate non-local contextual relations between complementary photon polarizations by adapting the entanglement and the local polarizations of a two-photon sta…
A possible solution to the which-way problem of quantum interference
Holger F. Hofmann, Tomonori Matsushita, Shunichi Kuroki +1
It is commonly assumed that the observation of an interference pattern is incompatible with any information about the path taken by a quantum particle. Here we show that, contrary…
Experimental investigation of the relation between measurement uncertainties and non-local quantum correlations
Kengo Matsuyama, Holger F. Hofmann, Masataka Iinuma
Bell's inequalities are defined by sums of correlations involving non-commuting observables in each of the two systems. Violations of Bell's inequalities are only possible because…
