the statement “The quantum state of a qubit is obtained by reading across a row … |0011>” seems quite problematic to me.
First, the q...

“The top six cells in each qubelet column are identical to those shown in” should be “the top seven cells…”. q[0] to q[6] i...

Stated: The NOT (X) gate is equivalent to the U3(pi, pi, 0, ) gate.
I tried that in the U3 matrix, but I got a different r...

(a+ib)^2 = a^2 + 2iab - b^2, not a^2 + 2iab + b^2.
In the next line, c = a^2 - b^2, not a^2 + b^2.

It states the two matrices being multiplied are A(Z) and A(CNOT). They should be A(CZ) and A(CNOT). The next line where the matrices are ...

At the end of page 65, ‘The target is the qubit in the q[5] register’, it should be the q[4] register.
