In this presentation, David Ittah presents Catalyst: an AOT/JIT compiler for hybrid classical-quantum programs, with integration into the Python ML ecosystem and the PennyLane quantum programming framework. A new quantum MLIR dialect (on top of existing MLIR dialects) provides the core IR for the compiler, and enables classical and quantum optimization, code generation, and automatic differentiation at the IR level.
