  If the system is known to be in one of two non-orthogonal quantum states,
$|\psi_1\rangle$ or $|\psi_2\rangle$, $\mathcal{PT}$-symmetric quantum
mechanics can discriminate them, \textit{in principle}, by a single
measurement. We extend this approach by combining $\mathcal{PT}$-symmetric and
Hermitian measurements and show that it's possible to distinguish an arbitrary
number of pure quantum states by an appropriate choice of the parameters of
$\mathcal{PT}$-symmetric Hamiltonian.
