If you're one of those people, or you'd just like to talk about 
the topic in general, please do reach out to me. I'd love to talk 
shop :)

Quantum CPU before x86_128 ? what do you think ?
I really think that x86_64 is the last "classic architecture". 
Intel will never make x86 with 128 bits addresses. Qbytes will 
raise before.

I don't know which will come first, but QPUs will not obsolete 
CPUs and GPUs. QPUs are not just faster CPUs. In a very similar 
manner to how GPUs are better than CPUs for some (but not all) 
tasks, QPUs will be better for a number of problems, but many 
algorithms will not see any benefit from use of a QPU. Future 
computers will have a CPU, GPU, and QPU, each used in tandem for 
the things each is good at.

My understanding of QPUs agrees with this - they're a 
fundamentally different usage model, and using them as the 
primary processor in a system is infeasible (right now) at 
present.

Hi Mithun!

You should look at the two following talks:
https://fosdem.org/2016/schedule/event/llvm_aap/
https://fosdem.org/2016/schedule/event/llvm_aapsim/

This can help you with how to use LLVM. The talks about a 
somewhat similar project.

Regards,
Kai

Thanks Kai!

I briefly looked at the "writing your own backend" articles on my 
flight home, but it was a little too much for my poor jetlagged 
brain to handle :) I'll definitely check those talks out.
