Source code InfoField | The following Mathematica code shows the equality: codeR[x_, y_, z_] := MatrixExp[-I/2 Sum[{x, y, z}[[i]] * PauliMatrix[i], {i, 3}]];
I2 = IdentityMatrix[2];
A_⊗ B_ := KroneckerProduct[A, B];
Z = R[0, 0, Pi];
MRZ = R[0, 0, -Pi/2];
RY = R[0, Pi/2, 0];
MRY = R[0, -Pi/2, 0];
SqrtSwap = MatrixPower[{{1,0,0,0}, {0,0,1,0}, {0,1,0,0}, {0,0,0,1}}, 1/2];
(MRZ⊗(MRY.MRZ)).SqrtSwap.(Z⊗I2).SqrtSwap.(I2⊗RY) // MatrixForm
