Quantum Computing: clockwise or anticlockwise (page 231)

Stated: “The S gate then rotates the triangle |1> qubelet 90 degrees, or a quarter turn clockwise”. The figure turns it anticlockwise. Elsewhere in the book, you state the S gate turns the |1> qubelet anticlockwise.

Hi,
The S-gate turns the |1> qubelet a quarter turn anti-clockwise.
The sentence is incorrect.

Thanks,
