quilc VS Vacietis

Yes, they use it for their quantum compiler, at RHL Laboratories (it was maybe initiated even at Rigetti). https://github.com/quil-lang/quilc

QUILC is probably the most interesting project. It is an open-source automatic, retargetable, optimizing compiler for Quil. It can take nearly any quantum computer architecture description and compile+optimize a Quil program for that architecture.

The QVM does all manner of quantum computer simulations. It specifically simulates a Quil program, with both classical and quantum operators. The QVM has lots of different modes of operation:

You can do this with a compiler like quilc. A program like

This is a new physical implementation of a particular mathematical operation, on a specific modality of qubit. The same mathematical operation can be computed on any other quantum computer in production today; very easily so if you use a compiler like QUILC [0].

For people who maybe already have a job, just want to dip their toes in, or some other life thing that prohibits them from being employed, I’ve done pro bono mentorship sessions to interested individuals, helping them contribute to open source software around this stack, like the quantum compiler. Always happy to discuss that for serious applicants.

compiler code

Yes, simulator, compiler, paper is some of it.

Speaking about Common Lisp, the only commercial-level compiler implementation that I know of is https://github.com/rigetti/quilc by /u/stylewarning et al.

Yes. Not because of the developer, but because of how extremely flexible and dynamic the Lisp-family languages are. The power and joy of Lisp is in how it's almost a meta-language, so every project can become its own EDSL. The most famous (infamous?) example of this is Vacietis[2], which is a Common Lisp library that allows C code to be imported directly(!!).

[0] IIRC the Yesod framework's Warp does well on benchmarks, and when you look at code like https://github.com/yesodweb/wai/blob/master/warp/Network/Wai... you can see the lengths they had to go through to work around the choice of implementation language.

[1] Go has a garbage collector, but exposes the stack/heap distinction more directly than Haskell, so it's easier to write allocation-free code in hot paths.

racket and common lisp both offer reader interfaces which allow parsing non-s-expression languages. see https://github.com/vsedach/Vacietis , a c compiler implemented in common lisp which uses the common lisp reader.

Very funny. One might be interested in e.g. Vacietis which does manage to compile enough of C correctly to a higher level language (in this case, Common Lisp) to be interesting.

================

Vacietis is a C compiler for Common Lisp systems.

Vacietis works by loading C code into a Common Lisp runtime as though
