Thank you for your explanation, Peter. 30 trillion of something is quite a lot! In fact it's not easy to imagine that amount of object would fit in a laptop's memory.

Is there some technique involved like succinct data structure, shared data structure or streaming write to disk?

I'm also interested in Quipper's "scalability" in classical sense, i.e. ability to utilize multi-core and/or distributed computation environments.

Dear Takayuki,

thanks for your interest! I hope you'll get a chance to play with
Quipper.

By "scalable", we mean that we have used Quipper to generate circuits
with over 30 trillion gates. So it's not just a toy that works for
small examples.

Best wishes, -- Peter
