It is a powerful tool which is usually used for quantum ciucuits simplification. `ZX.jl` will implement quantum ciucuits simplification algorithms based on ZX-calculus in pure Julia. Also, it will provide interfaces to import and export quantum circuits to the form of YaoIR, an intermediate representation for quantum programs in the [`Yao.jl`](https://github.com/QuantumBFS/Yao.jl). So that one can get quantum circuits with higher performance automatically when designing quantum programs with `Yao.jl`. - -## Why this project? - -Since Shor's factoring quantum algorithm, people believe that quantum computers are more powerful than classical computers and quantum algorithms are more efficient than classical algorithms on some computational tasks. The basic model for describing quantum algorithms is the quantum circuit. And what quantum compiler do is compiling quantum programs to quantum circuits. - -On the one hand, as quantum hardware developing is so difficult, only limited number of qubits will be available and only small size of quantum circuits can be run on quantum devices in the near-term future. On the other hand, simulating quantum computer on classical computer needs exponential resources. Simpler circuits will help us developing more efficient quantum simulation algorithms. If we have good quantum ciucuits simplification algorithms in the quantum compiler, we can get faster quantum algorithms. - -ZX-calculus is a powerful tool for quantum ciucuits simplification. And lots of algorithms are developed based on it. There exist a Python implementation [`PyZX`](https://github.com/Quantomatic/pyzx). With `PyZX`, one can simplify quantum circuits with ZX-calculus. Several input and output forms of quantum circuits are provided and visualization of quantum circuits are available. -But there is no Julia implementation of these algorithms. In Julia, `Yao.jl` is a high-performance and extensive package for quantum software framework. However, only simple ciucuits simplification algorithms are available in `Yao.jl`. If one want to develop better ciucuits simplification algorithms to the quantum compiler in `Yao.jl`, a high-performance pure Julia implementation of ZX-calculus is necessary. - -## Technical Details - -`ZX.jl` will be a package for ZX-calculus which any Julia user can install. With `ZX.jl`, one will be able to develop quantum circuits simplification algorithms, which are very important for current quantum algorithm designing, in pure Julia. - -The implementation of ZX-calculus consist of three levels. - -The first level is the backend data structures for representing ZX-diagrams, the basic objects in ZX-calculus. In general, ZX-diagrams are multigraphs with extra information of their edges and vertices, (for example, phases of vertices). Fortunately, there has been [`LightGraphs.jl`](https://github.com/JuliaGraphs/LightGraphs.jl) for simple graphs already. And I have developed [`Multigraphs.jl`](https://github.com/QuantumBFS/Multigraphs.jl) as a multigraph extension for `LightGraphs.jl`. Hence, problems of representing ZX-diagrams can be solve by using these existing packages. - -The second level is the basic rules in ZX-calculus. These basic rules define equivalence relations between ZX-diagrams and can be found in [this paper](https://arxiv.org/abs/1903.10477). In ZX-calculus, All simplification algorithms are based on these basic rules. These rules can be implemented by operating the backend multigraphs and extra information of ZX-diagrams. - -The third level is the quantum ciucuits simplification algorithms. These algorithms can be implemented by using basic rules. For example, the state-of-art algorithm for reducing T-count. All these algorithms can be found on [ZX-calculus](http://zxcalculus.com/publications.html). - -As an application, I'm going to develop interfaces for importing and exporting quantum circuits in the form of YaoIR. So that, `Yao.jl` can simplify quantum circuits defined by users when compiling quantum algorithms. - -For data visualization, I will provide ways to plot ZX-diagrams and quantum circuits. This will based on the graph visualization tool [`GraphPlot.jl`](https://github.com/JuliaGraphs/GraphPlot.jl). - -## Schedule of Deliverables - -### Before Community Bonding Period - -**April 1, 2020 - April 27, 2020** - -Read articles on ZX-calculus.
