This sample introduces entanglement.

To run this application, simply run mvn clean javafx:run

There is no output on the console, but the quantum circuit and probability distribution is shown:

This sample introduces entanglement. A Bell state is created by applying a Hadamard gate to a qubit, and a CNot gate to this qubit and another qubit. As a result, both qubits are now entangled. Their measurements are not independent from each other anymore. Only the |00> or the |11> outcome is possible.

You can learn more about this sample in Chapter 5 of Quantum Computing for Java Developers. It is discussed in 5.6: "Creating a Bell state: dependent probabilities"
