Two time localization
Although quantum evolution equations are first order in time it is possible to define a state through partial information at multiple times. We consider the specification of position at two times and for a given Hamiltonian seek the wavefunction that minimizes the sum of the spreads at those times. We also study the time dependence of that minimal spread for a variety of Hamiltonians and boundary conditions.
