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.
