You can get an API key from Rigetti Forest if you don't have one.

Hello World

The Hello World of quantum programming is preparing and measuring the Bell state. Let's do that!

WavefunctionSimulator wvfsim = new WavefunctionSimulator();
	
Program p = new Program(g.H(0),
			g.CNOT(0,1));   

System.out.println("Bell state " +  Wavefunction.bra_ket(wvfsim.wavefunction(p)));

These qubits are entangled. The result will be

Bell state 0.71|00> + 0.71|11>

This Bell pair will always measure to the same values.

p.measure(0,0);
p.measure(1,1);
	
System.out.println("Bell state after measurement " + QVMConnection.run(p, Arrays.asList(0, 1)));

If one qubit measures to 1, the other will be 1 and vice versa.
