Comment on “Control landscapes are almost always trap free: a geometric assessment”. (English) Zbl 1411.81106

J. Phys. A, Math. Theor. 51, No. 50, Article ID 508001, 8 p. (2018).
Summary: We analyze a recent claim that almost all closed, finite dimensional quantum systems have trap-free (i.e. free from local optima) landscapes [B. Russell et al., ibid. 50, No. 20, Article ID 205302, 19 p. (2017; Zbl 1367.81074)]. We point out several errors in the proof which compromise the authors’ conclusion.
