Useful Majorana star related functions.

Functions

antipodal(to_invert[, from_cartesian, …])	If given an extended complex coordinate, takes the point to its antipode on the sphere via the map:
basis(d, i[, up])	Similar to pauli_eigenstate, only parameterized by dimension.
pauli_eigenstate(j, m, direction)	Returns eigenstates of Pauli operators.
poleflip(to_flip[, from_cartesian, …])	Flips the pole of projection.
spherical_inner(a, b)	\(\langle a \mid b \rangle\) via an integral over the sphere.
spin_coherent(j, coord[, from_cartesian, …])	Returns the spin-j coherent state which is defined by having all its Majorana stars located at a single point on the sphere.
