Query: Tighter Einstein-Podolsky-Rosen steering inequality based on the sum
  uncertainty relation   We consider the uncertainty bound on the sum of variances of two incompatible
observables in order to derive a corresponding steering inequality. Our
steering criterion when applied to discrete variables yields the optimum
steering range for two qubit Werner states in the two measurement and two
outcome scenario. We further employ the derived steering relation for several
classes of continuous variable systems. We show that non-Gaussian entangled
states such as the photon subtracted squeezed vacuum state and the
two-dimensional harmonic oscillator state furnish greater violation of the sum
steering relation compared to the Reid criterion as well as the entropic
steering criterion. The sum steering inequality provides a tighter steering
condition to reveal the steerability of continuous variable states.
