Compiling a Q# Subset to QASM 3.0 in TypeScript via a JSON Based IR

TL;DR

This paper presents a TypeScript-based compiler toolchain that translates a subset of Q# quantum programming language into QASM 3.0, enabling web-compatible quantum program compilation with a custom lexer, parser, and compiler.

Contribution

The main novelty is implementing a Q# to QASM 3.0 compiler in TypeScript, facilitating web deployment and extending existing quantum compilation tools.

Findings

Successfully compiles a subset of Q# to QASM 3.0

Works with various Q# programs and compares favorably to existing tools

Enables quantum programming in web environments

Abstract

We implement a compile toolchain from Q# to QASM 3.0 including a full-featured lexer and parser implementation, as well as a compiler that supports a subset of Q# features. The lexer, parser and compiler are shown to work with various input Q# programs and the implementation is compared against existing Q# compile tools. Unlike the Microsoft implementation of the official Q# compile toolchain, our implementation is written in TypeScript in order to port functionality to web environments.
