difference between paper and code in quan_layer

[EwainPeng]

Hi~ I have a liitle puzzled about a difference between paper and code in quan_layer.py.
In paper, when B = 4 P0∈{0,2^0,2^-2,2^-4} (show in example in 2.2)
But in code quan_layer.py line 23: base_b.append(2 ** (-2 * i - 2)), when i range(3) we have P0∈{0,2^-2,2^-4,2^-6}
I am a little puzzled about it, thanks a lot!

I have the same question as EwainPeng.
Why the sum of n PoT terms of each level is different from the paper?
Looking forward to your reply！
