        }
    }

    // Basic quantum operations

    // Hadamard gate: Puts the qubit into a superposition state
    static Qubit hadamardGate(Qubit qubit) {
        Complex newZero = qubit.zeroState.add(qubit.oneState).divide(Math.sqrt(2));
        Complex newOne = qubit.zeroState.subtract(qubit.oneState).divide(Math.sqrt(2));

        Qubit qubit = new Qubit(new Complex(1, 0), new Complex(0, 0));

        // Apply Hadamard gate to put qubit into a superposition of states
        Qubit superposition = hadamardGate(qubit);

        // Measure the qubit multiple times to see the probability distribution
        int zeroCount = 0;
        int oneCount = 0;
        for (int i = 0; i < 1000; i++) {

            if (measurement == 0) {

            } else {
                oneCount++;
            }
        }

        // Output the qubit state after Hadamard and measurement results
        System.out.println('Quantum state after Hadamard gate: ' + superposition);
        System.out.println('Measurement results: |0> occurred ' + zeroCount + ' times, |1> occurred ' + oneCount + ' times.');

Measurement results: |0> occurred ~500 times, |1> occurred ~500 times.

Code Explanation:

Okay, let’s break down this piece of work.

Firstly we import the required classes. Apache Commons Math for complex number operations ’cause, you know, quantum states are in that realm of complex amplitudes. Then we roll in Random to simulate measurement randomness.

Our Qubit class encapsulates the concept of a quantum bit, with complex amplitudes for its binary states |0> and |1>. Normalizing the qubit’s state ensures that the sum of the probabilities (magnitudes squared of the amplitudes) equals one – just like how a well-behaved qubit should act.

In the quantum world, things are literally not so binary. So, we introduce the Hadamard gate, which kicks a qubit into a superposition, creating equal probabilities for measuring |0> or |1> upon observation. That’s what our hadamardGate method is all about.

Next, we’ve got the measure method. This bad boy decides the fate of our qubit upon measurement by collapsing its superposition to either |0> or |1> based on the calculated probabilities. And yeah, it’s all down to a pseudo-random number. Classic quantum unpredictability!

Now, let’s talk about the main act. We start with a qubit proudly in the |0> state. But not for long! We hit it with the hadamardGate. Now it’s in a superposition, not sure if it’s coming or going, which we love to see.

We then run a thousand measurements because we’re thorough like that. Counting how often we get a zero or a one gives us an empirical slap of the probability distribution that our nifty quantum state suggested.

Finally, we print out the transformed quantum state post-Hadamard action and the measurement stats. If all’s well with the universe, we should see a roughly 50-50 split between zeros and ones because quantum mechanics is all about that balance. Or is it? Well, that’s quantum uncertainty for ya!

And that’s all folks! Keep coding and stay quantum! ✨👩‍💻🌌
