Quantum Computing samples in Java

This repository contains the source code for the samples discussed in Quantum Computing for Developers

It is based on the Strange Quantum Simulator, which provides an execution environment for quantum algorithms in Java.
Some samples use a UI, e.g. to visualize the quantum circuit. In that case, StrangeFX is used, which is a JavaFX-based framework that allows the visualisation of quantum circuits.

The samples in this repository correspond to the chapters in the book. Don't worry if you don't have the book, you can still run the samples.
