Hi,
I just compared ralph-cnot circuit displayed in Jupyter vs. plain-text mode.
I think plain text is incorrect, the upper and lower BS act on wrong modes.
Thanks
Jan

Hello,
There is actually no problem here. In the text drawing, the photon from the herald0 is sent on mode 1 by the first PERM and put back on mode 4 by the last PERM. It’s just that representing permutations is ascii is too difficult so we just represent them with a cross without the detail of what is really happening.
Regards,
