As quantum computing is approaching a phase of quantum utility, a need for new compiler toolchains arises to support recent hardware breakthroughs. This talk will present an overview of our MLIR-based compiler infrastructure for quantum photonic networks and explore its design aimed at overcoming the limitations of current quantum devices and support distributed quantum processing. We also aim to provide insights into the specifics of compiler development for quantum computing, guided by non-obvious user priorities and the nuanced behavior of quantum hardware and control devices. The discussion spans from the challenges of adoption of a programming model adequate for extending heterogeneous computing and distributed systems with quantum devices to interfacing with different categories of quantum computing users, via well-established in the field frontends and with the prospect of adopting smoother ways of leveraging quantum MLIR-based compilers and tools. We are exploring the LLVM-based compiler toolchain for quantum computing from low-level details to high-level concepts, from code generation for quantum experiments in real-time setup and for multiple hardware designs and system generations to architectural concerns of supporting resource-efficient scalable quantum computing platform.
