Abstract:
We consider the problem of reconstructing a state (i.e., a positive unit-trace operator) from incomplete information on its optical tomogram. In the case, when a (pure) state is determined by a function representing a linear combination of N ground and excited states of a quantum oscillator, we propose a technique for reconstructing this state from N values of its tomogram. For N=3 we find an exact solution to the problem under consideration.
Keywords:
state, optical tomogram, eigenfunctions of integral operator.
