Bulk physical matter displays one set of characteristics. Deliberate
arrangement of atoms of the same elements as the bulk matter can
display very different characteristics -super-conductance, strange
optical properties etc.
These are physical arrangements of matter.
The simple hypothetical quantum computers we describe today use yet
another level of organisation. By deliberately contriving situations
where the rules of quantum mechanics interact to perform computation.
This is also Physics but I would not describe it as physical.

I didn't say they did.
