Hi,
Thanks for your question. We define alpha as the clipping threshold for the quantization. Not the step size between two adjacent quantization levels. So we expect the tensor divide by alpha will lie in [0, 1], and then scale them to [0, 2**b-1] so that round() function can compute the corresponding integers. After, rounding-to-nearest, we scale the integers back to original range, also known as the de-quantization as you mentioned.
