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…
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…
External quantum fluctuations select measurement contexts
Jonte R. Hance, Ming Ji, Tomonori Matsushita +1
Quantum paradoxes show that the outcomes of different quantum measurements cannot be described by a single measurement-independent reality. Any theoretical description of a quantum…
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…
Contextuality, Coherences, and Quantum Cheshire Cats
Jonte R. Hance, Ming Ji, Holger F. Hofmann
We analyse the quantum Cheshire cat using contextuality theory, to see if this can tell us anything about how best to interpret this paradox. We show that this scenario can be anal…
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…
Quantitative relations between different measurement contexts
Ming Ji, Holger F. Hofmann
In quantum theory, a measurement context is defined by an orthogonal basis in a Hilbert space, where each basis vector represents a specific measurement outcome. The precise quanti…
Characterization of the non-classical relation between measurement outcomes represented by non-orthogonal quantum states
Ming Ji, Holger F. Hofmann
Quantum mechanics describes seemingly paradoxical relations between the outcomes of measurements that cannot be performed jointly. In Hilbert space, the outcomes of such incompatib…
