[not verified in body] Other circuits designed for experimentation related to quantum systems can be instrumentation and sensor based.It was introduced by Robert Smith, Michael Curtis, and William Zeng in A Practical Quantum Instruction Set Architecture.An open source project developed by Google, which uses the Python programming language to create and manipulate quantum circuits.An open source project developed by Rigetti, which uses the Python programming language to create and manipulate quantum circuits.As well as the ability to create programs using basic quantum operations, higher level algorithms are available within the Grove package.Written mostly in the Python programming language, it enables users to formulate problems in Ising Model and Quadratic Unconstrained Binary Optimization formats (QUBO).[24][25] An open source project developed at the Institute for Theoretical Physics at ETH, which uses the Python programming language to create and manipulate quantum circuits.Qibo is a modular framework which includes multiple backends for quantum simulation and hardware control.As well as the ability to create programs using basic quantum operations, higher level tools for algorithms and benchmarking are available within specialized packages.Furthermore, it is platform independent, since it offers alternative compilation of elementary functions down to the circuit level, based on device-specific gate sets.[39][40] Three simulators are provided - one in the Fock basis, one using the Gaussian formulation of quantum optics,[41] and one using the TensorFlow machine learning library.Ket[48] is an open-source embedded language designed to facilitate quantum programming, leveraging the familiar syntax and simplicity of Python.The language is part of the Classiq platform and can be used directly with its native syntax, through a Python SDK, or with a visual editor, all methods can take advantage of the larger library of algorithms and the efficient circuit optimization.It is built on top of the LLVM Compiler Infrastructure to perform optimizations on Scaffold code before generating a specified instruction set.[61][62] Silq is a high-level programming language for quantum computing with a strong static type system, developed at ETH Zürich.[66][67] Higher-order quantum programming languages, based on lambda calculus, have been proposed by van Tonder,[68] Selinger and Valiron[69] and by Arrighi and Dowek.[71] It is currently being developed by the Quantum Architectures and Computation Group (QuArC)[72] part of the StationQ efforts at Microsoft Research.[75][66] Unlike Selinger's QPL, this language takes duplication, rather than discarding, of quantum information as a primitive operation., and is not to be confused with the impossible operation of cloning; the authors claim it is akin to how sharing is modeled in classical languages.In 2003, André van Tonder defined an extension of the lambda calculus suitable for proving correctness of quantum programs.
