This is a preliminary version. This package can be used to perform some calculations in quantum parameter estimation. Currently we have two versions.

1. Independent version: It only requires the basic packages like numpy.

2. qutip version: it is based on the package QuTiP (http://qutip.org/).

Functions included:

1. Quantum Fisher information (matrix)

Control algorithm included:

1. GRAPE
