PauliMeasurementBasis

class PauliMeasurementBasis(mitigator=None)

Standard Pauli measurement basis.

This basis has 3 indices each with with 2 measurement outcomes. The corresponding single-qubit measurement circuits and outcome POVM matrices are:

Table 1 Single-qubit measurement circuits and POVM matrices

Index	Basis	Circuit	Outcome	POVM Matrix
0	Z	-[I]-	0	[[1, 0], [0, 0]]
			1	[[0, 0], [0, 1]]
1	X	-[H]-	0	[[0.5, 0.5], [0.5, 0.5]]
			1	[[0.5, -0.5], [-0.5, 0.5]]
2	Y	-[SDG]-[H]-	0	[[0.5, -0.5j], [0.5j, 0.5]]
			1	[[0.5, 0.5j], [-0.5j, 0.5]]
