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…
Uncertainty limits for post-selected metrology
Ming Ji, Holger F. Hofmann
For unitary transformations, the quantum Fisher information (QFI) of a pure state is given by the uncertainty of the generator in that state. In post-selected metrology, the QFI is…
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…
Enhanced quantum parameter estimation based on the Hardy paradox
Ming Ji, Yuxiang Yang, Holger F. Hofmann
Statistical paradoxes such as the Hardy paradox and the enhancement of phase estimation via post-selection both draw upon the same non-classical features of quantum statistics desc…
Quantum coherence and negative quasi probabilities in a contextual three-path interferometer
Holger F. Hofmann
Basic quantum effects are often illustrated using single particle interferences in two-path interferometers. A wider range of non-classical phenomena can be illustrated using three…
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…
Tracing quantum correlations back to collective interferences
Ming Ji, Jonte R. Hance, Holger F. Hofmann
In this paper, we investigate the possibility of explaining nonclassical correlations between two quantum systems in terms of quantum interferences between collective states of the…
Contextual particle propagation in a three-path interferometer
Holger F. Hofmann
Quantum information is based on the apparent contradictions between classical logic and quantum coherence described by Kochen-Specker contextuality. Surprisingly, this contradictio…
