PennyLane Catalyst

Catalyst is a JIT compiler for hybrid quantum programs written in PennyLane. The `@qjit` decorator compiles entire quantum-classical workflows — including conditionals, loops, and gradients — to a custom MLIR quantum dialect, then lowers to LLVM and QIR for execution against Lightning, AWS Braket, and an expanding set of QPUs. Apache 2.0.
