Introducing BRAT: A Functional Programming Language for Quantum-Classical Hybrid Programs

Explore BRAT, a functional programming language designed for interleaving quantum and classical execution, in this 22-minute conference talk from ACM SIGPLAN's PLanQC'24. Discover the language's unique syntax that enables juxtaposition of different circuit parts and its use of type-level parameters for program reasoning during type checking. Learn through various examples, including illegal programs, as presenters Ross Duncan, Mark Koch, Alan Lawrence, Conor McBride, and Craig Roy demonstrate BRAT's features, composition capabilities, and safety guarantees. Gain insights into the future directions of this innovative quantum-classical programming language.
