An installation-free web-tool by the Institute for Integrated Circuits at the Johannes Kepler University Linz which visualizes quantum decision diagrams and allows to explore their behavior when used in design tasks such as simulation, synthesis, or verification. The tool is hosted online at https://iic.jku.at/eda/research/quantum_dd/tool/.

MQT DDVis allows users to interactively learn how decision diagrams can be used in quantum computing, e.g., to

• compactly represent quantum states and efficiently simulate quantum circuits,
• compactly represent the functionality of quantum circuits,
• verify the equivalence of two circuits in an efficient fashion.

To run DDVis locally, you will require a C++ compiler, CMake, Node.js, and NPM (probably still missing something). The following commands will build the app and start it. Open your browser at localhost:3000 to access the user interface.

$ git clone --recurse-submodules [email protected]:cda-tum/ddvis.git  
$ cd ddvis
ddvis $ npm install
ddvis $ npm run-script run
[...]
> node ./bin/www

(Tested under Ubuntu 20.04 with npm installed via sudo snap install node.)
