Hydrodynamical quantum state reconstruction
arXiv:quant-ph/9805046 · doi:10.1103/PhysRevLett.80.5461
Abstract
The density matrix of a nonrelativistic wave-packet in an arbitrary, one-dimensional and time-dependent potential can be reconstructed by measuring hydrodynamical moments of the Wigner distribution. An n-th order Taylor polynomial in the off-diagonal variable is obtained by measuring the probability distribution at n+1 discrete time values.
