That's the justification the designer of the circuit I linked to
stated for why they decided to use a separate circuit made from
discrete components. USB devices using similar circuits can also be
purchased for the same reason. Anyway, you don't need a quantum
computer to do it.

How can you be sure anything works as advertised? There's always
the risk of backdoors in the Intel Management Engine enabling all
sorts of possible attacks. That designer likes FPGA-based CPUs for
this reason, although there's still a small risk that the FPGAs
could be maliciously designed to specifically sabotage that
approach too.
