Violation of Continuous-Variable Einstein-Podolsky-Rosen Steering with Discrete Measurements
Violation of Continuous-Variable Einstein-Podolsky-Rosen Steering with Discrete Measurements
In this Letter, we derive an entropic Einstein-Podolsky-Rosen (EPR) steering inequality for continuous variable (CV) systems using only experimentally measured discrete probability distributions and details of the measurement apparatus. We use this inequality to witness EPR steering between the positions and momenta of photon pairs generated in spontaneous parametric downconversion …
