Depolarizing noise doubles the number of non-analytic points in the Loschmidt echo at dynamical phase transition times in the transverse-field Ising model, inducing an inherent error that zero-noise extrapolation cannot mitigate.
WYSI detects quantum phase transitions in the Heisenberg XYZ chain with DM interaction, revealing a factorization volume in the gapless chiral phase and a three-phase diagram.
