Query: Quantum State Tomography Using Successive Measurements   We describe a quantum state tomography scheme which is applicable to a system
described in a Hilbert space of arbitrary finite dimensionality and is
constructed from sequences of two measurements. The scheme consists of
measuring the various pairs of projectors onto two bases --which have no
mutually orthogonal vectors--, the two members of each pair being measured in
succession. We show that this scheme implies measuring the joint
quasi-probability of any pair of non-degenerate observables having the two
bases as their respective eigenbases. The model Hamiltonian underlying the
scheme makes use of two meters initially prepared in an arbitrary given quantum
state, following the ideas that were introduced by von Neumann in his theory of
measurement.
