Dear Haskellers, we are proud to announce the first public release of Quipper, an embedded, scalable functional programming language for quantum computing. The Quipper distribution is available here:
http://www.mathstat.dal.ca/~selinger/quipper/ and includes extensive documentation, as well as seven worked examples of non-trivial quantum algorithms from the literature. Quipper is embedded in Haskell and makes use of many advanced features of the GHC Glasgow Haskell Compiler. Here are some highlights: * High-level circuit description language, including both gate-by-gate descriptions and powerful higher-order operators for assembling and manipulating circuits. * A monadic semantics, allowing for a mixture of procedural and declarative programming styles. * Built-in facilities for automatic synthesis of reversible quantum circuits, including from classical Haskell code. * Support for hierarchical circuits. * Extensible quantum data types. * Programmable circuit transformers * Support for a dynamic lifting operation to allow circuit generation to depend on parameters generated at circuit execution time. * Extensive libraries of quantum functions, including: libraries for quantum integer and fixed-point arithmetic; the Quantum Fourier transform; an efficient Qram implementation; libraries for simulation of pseudo-classical circuits, Stabilizer circuits, and arbitrary circuits; libraries for exact and approximate decomposition of circuits into specific gate sets. Comments are welcome! Alexander S. Green Peter LeFanu Lumsdaine Neil Julien Ross Peter Selinger Benoit Valiron
