One of the most productive applications of the recent extension of
applicability of unitary quantum theory to operators $H=-d^2/dx^2+V(x) \neq
H^\dagger$ (where, typically, the spectrum is real but where the coordinate is
not observable anymore, $x \in \mathbb{C}$) has been found in the innovative
constructions of bound states even in singular pote...

... shows Our subsequent tests of the performance of the perturbation series (i.e., of the pre- cision of the N−th order perturbative ground-state approximants E [N ] ) were based on the direct comparison with the RPM-based numerical results (of any prescribed precision). A sufficiently representative sample of these comparisons is summarized in Fig. 1. We used there a characteristic "intermediate" coupling constant R = 2 and the same values of the exponents m and n as in Table 1 ...

We present a brief review of discrete structures in a finite Hilbert space, relevant for the theory of quantum information. Unitary operator bases, mutually unbiased bases, Clifford group and stabilizer states, discrete Wigner function, symmetric informationally complete measurements, projective and unitary t--designs are discussed.
