"Nonlocality-of-a-single-photon" based Quantum Key Distribution and Random Number Generation schemes and their device-independent security analysis
Konrad Schlichtholz, Bianka Woloncewicz, Tamoghna Das +2
The question of ``non-locality of a single photon'', which started with a paper by Tan, Walls and Collett (TWC, 1991) stirred a thirty years long debate. This hampered attempts to…
Quantitative non-classicality of mediated interactions
Ray Ganardi, Ekta Panwar, Mahasweta Pandit +2
In plethora of physical situations one can distinguish a mediator -- a system that couples other, non-interacting systems. Often the mediator itself is not directly accessible to e…
Improved entanglement indicators for optical fields and its application in the event-ready experiment for bright squeezed vacuum with induced non-gaussianity
Bianka Woloncewicz, Tamoghna Das, Marek Żukowski
Better versions of separability conditions for four mode optical fields, i.e. two beams with two modes of mutually orthogonal polarization are given. Our conditions involve varianc…
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…
