PauliPreparationBasis

class PauliPreparationBasis

Minimal 4-element Pauli measurement basis.

This is a minimal size 4 preparation basis where each qubit index corresponds to the following initial state preparation circuits and density matrices:

Index	State	Preparation Circuit	Density Matrix
0	Zp	-[I]-	[[1, 0], [0, 0]]
1	Zm	-[X]-	[[0, 0], [0, 1]]
2	Xp	-[H]-	[[0.5, 0.5], [0.5, 0.5]]
3	Yp	-[H]-[S]-	[[0.5, -0.5j], [0.5j, 0.5]]
