Hydrodynamical Quantum State Reconstruction
Lars M. Johansen · Kluwer Academic Publishers eBooks · 2005
A new and general quantum state reconstruction method is proposed. It can be applied to reconstruct the state of a particle in an arbitrary, time-dependent potential. The state is reconstructed by measuring the position probability distribution at n + 1 different time values. This yields an n-th order Taylor polynomial expansion of the density matrix in the off-diagonal variable.
