流体力学量子态重构

Hydrodynamical quantum state reconstruction

Lars M. Johansen

摘要:

通过测量Wigner分布的流体动力学矩,可以重建任意一维含时势中非相对论性波包的密度矩阵。通过测量n+1个离散时间值的概率分布,得到非对角变量的n阶泰勒多项式。

英文摘要:

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.
