Controlled asymmetry of EPR steering with an injected non-degenerate optical parametric oscillator
arXiv:1707.04691 · doi:10.1103/PhysRevLett.119.160501
Abstract
We propose and analyse a nonlinear optical apparatus in which the direction of asymmetric steering is controllable within the apparatus, rather than by adding noise to measurements. Using a nondegenerate parametric oscillator with an injected signal field, we show how the directionality and extent of the steering can be readily controlled for output modes which can be up to one octave apart. The two downconverted modes, which exhibit the greater violations of the steering inequalities, can also be controlled to exhibit asymmetric steering in some regimes.
