Nowadays photon-number resolving weak-field homodyne measurements allow realization of emblematic gedankenexperiments revealing correlations of optical fields. This covers experiments on (a) excitation of a pair of spatial modes by a single photon, and (b) two spatial modes in a weakly squeezed vacuum state, involving constant local oscillator strengths. Proving Bell nonclassicality of such correlations demands measurements of complementary observables. We show that typical arrangement of weak…

Optimal Interferometry for Bell Nonclassicality Induced by a Vacuum–One-Photon Qubit

Bell nonclassicality of a single photon superposition in two modes, often referred to as ‘nonlocality of a single photon’, is one of the most striking nonclassical phenomena discussed in the context

Bosonic fields in states with undefined particle numbers possess detectable non-contextuality features, plus more

The paradoxical features of quantum theory are usually formulated for fixed number of particles. While one can now find a formulation of Bell’s theorem for quantum fields, a Kochen–Specker-type

On the Fidelity Robustness of CHSH–Bell Inequality via Filtered Random States

The theorem developed by John Bell constituted the starting point of a revolution that translated a philosophical question about the nature of reality into the broad and intense field of research of

Comment on ‘Single particle nonlocality with completely independent reference states’

We comment on the purported violation of local realism, by a single photon induced correlations between homodyne detectors, which one can find in: (2008) New J. Phys. 10 113024 [arXiv:0807.0109]. The
