About

staq is a modern C++ library for the synthesis, transformation, optimization and compilation of quantum circuits. staq is written in standard C++17 and has very low external dependencies. It is usable either through the provided binary tools, or as a header-only library that can be included to provide direct support for parsing & manipulating circuits written in the OpenQASM 2.0 circuit description language.

Inspired by Clang, staq is designed to manipulate OpenQASM 2.0 syntax trees directly, rather than through an intermediate representation which makes retrieving the original source code impossible. In particular, OpenQASM 2.0 circuits can be inspected and transformed (in most cases) without losing the original source structure. This makes staq ideally suited for source-to-source transformations, where only specific changes are desired. Likewise, this allows translations to other common circuit description languages and libraries to closely follow the OpenQASM 2.0 source.

Check out the Wiki for more information about the library and included tools.
