Query: Quenches near criticality of the quantum Ising chain---power and
  limitations of the discrete truncated Wigner approximation   The semi-classical discrete truncated Wigner approximation (dTWA) has
recently been proposed as a simulation method for spin-$1/2$ systems. While it
appears to provide a powerful approach which shows promising results in higher
dimensions and for systems with long-range interactions, its performance is
still not well understood in general. Here we perform a systematic benchmark on
the one-dimensional transverse-field Ising model and point to limitations of
the approximation arising after sudden quenches into the quantum critical
regime. Our procedure allows to identify the limitations of the semi-classical
simulations and with that to determine the regimes and questions where quantum
simulators can provide information which is inaccessible to semi-classics.
