Sequential propagation of a single photon through five measurement contexts in a three-path interferometer
Holger F. Hofmann
Quantum contextuality describes scenarios in which it is impossible to explain the experimental evidence in terms of a measurement independent reality. Here, I introduce a three-pa…
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…
Quantum interference effects determine contextual realities
Holger F. Hofmann
Quantum mechanics describes the relation between different measurement contexts in terms of superpositions of the potential measurement outcomes. This relation between measurement…
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…
Enhancement of broadband entangled two-photon absorption by resonant spectral phase flips
Baihong Li, Holger F. Hofmann
Broadband energy-time entanglement can be used to enhance the rate of two-photon absorption (TPA) by combining a precise two-photon resonance with a very short coincidence time. Be…
