Simple example programs using Silq

In this section, let's see some simple quantum circuits that can be implemented in Silq; mostly, we will be focusing our discussion on the quantum logic gates that we learned about in Chapter 2, Quantum Bits, Quantum Measurements, and Quantum Logic Gates.

Let's start with the Pauli X gate, which looks as follows in the Silq language:

def main() {
    return PauliX();
}
def PauliX() {
    x:=0:;
    return X(x);
}

The preceding program is fairly easy to understand and implement. You can see that the x qubit is initialized to 0, so the expected output should be 1. Figure 6.12 shows the output of this program:

Now, let's see the Pauli Y gate. The code for the Y gate is as follows:

def main() {
    return PauliY();
}
def PauliY() {
 ...
