I've got a PhD in physics and I have no idea what he's talking about here. Seems like the mainboard layout had issues at higher frequencies which is easily a 100% classical electromagnetism problem. Inductance, impedance and what have you. As another commenter alluded, its only 'quantum' in the sense that all semiconductor behavior is.
I think this is another case where 'quantum' is confused with 'apparently spooky.'
