Simplified Quantum Optical Stokes observables and Bell's Theorem
Konrad Schlichtholz, Bianka Woloncewicz, Marek Żukowski
We introduce a simplified form of Stokes operators for quantum optical fields that involve the known concept of binning. Behind polarization analyzer photon numbers (more generally…
Comment on `Single particle nonlocality with completely independent reference states'
Tamoghna Das, Marcin Karczewski, Antonio Mandarino +3
We comment on the purported violation of local realism, by a single photon induced correlations between homodyne detectors, which one can find in: New J. Phys. 10, 113024 (2008), […
On detecting violation of local realism with photon-number resolving weak-field homodyne measurements
Tamoghna Das, Marcin Karczewski, Antonio Mandarino +3
Non-existence of a local hidden variables (LHV) model for a phenomenon benchmarks its use in device-independent quantum protocols. Nowadays photon-number resolving weak-field homod…
Can single photon excitation of two spatially separated modes lead to a violation of Bell inequality via homodyne measurements?
Tamoghna Das, Marcin Karczewski, Antonio Mandarino +3
We reconsider the all-optical homodyne-measurement based experimental schemes that aim to reveal Bell nonclassicality of a single photon, often termed `nonlocality'. We focus on th…
No-go for device independent protocols with Tan-Walls-Collett `nonlocality of a single photon'
Tamoghna Das, Marcin Karczewski, Antonio Mandarino +3
We investigate the interferometric scheme put forward by Tan, Walls and Collett [Phys. Rev. Lett. {\bf 66}, 256 (1991)] that aims to reveal Bell non-classicality of a single photon…
