🐲 PyQIR

• $40 | Upgrade samples to ANTLR 4.10
• $175 | pyqir-evaluator should gracefully fail when bitcode contains unknown external functions
• $50 | Add mypy to CI
• $15 | Migrate to Rust 2021 Edition

PyQIR is a set of APIs for generating, parsing, and evaluating Quantum
Intermediate Representation (QIR). It
consists of the following components:

• pyqir-generator
  [examples]:
  
  
  Provides a Python API for generating QIR
  (bitcode and
  IR). It is intended to easily integrate
  the QIR toolchain into existing Python-based frontends.

• pyqir-evaluator
  [examples]:
  
  
  Provides an easy way to execute generated QIR. It contains the
  necessary just-in-time
  compilation
  infrastructure as well an extensibility mechanism to define what actions to
  perform when a gate is applied in Python.

• pyqir-parser:
  
  
  Provides a Python API for loading QIR for basic analysis and
  transformation.

• qirlib - a Rust library
  wrapping LLVM libraries for working with QIR that is used
  by the above Python packages.
