Tipler's ideas are, at the very least, sketchy. Even if there were a
big crunch, the notion that there would be an infinite amount of
computation possible in finite time seems to violate a lot of current
physics including the Beckenstein Bound. Of course, we now know that
there is not going to be a Big Crunch anyway.

Could Nanotechnology be used to create some kind of quantum computer
that would produce the same results?

I think you need to have at least three buzzwords involving
technologies few people understand before you can claim magic
properties.

More seriously, no, I don't think any of this changes anything. There
are still limits that prevent storage of infinite amounts of
information and computation within finite spaces. All quantum
computers get you is the ability to compute things with a faster big-O
than you otherwise could -- they don't allow you to violate the laws
of physics by doing infinite computation in finite time.
