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…
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…
