    "abstract": "A recent result about measurability of a quantum state of a single quantum\nsystem is generalized to the case of a single pre- and post-selected quantum\nsystem described by a two-state vector. The protection required for such\nmeasurement is achieved by coupling the quantum system to a pre- and\npost-selected protected device yielding a nonhermitian effective Hamiltonian.",
