What does the concept of superposition in quantum mechanics describe?

The limitation of a quantum system to exist only in one predefined, observable state.

The phenomenon of a quantum system to be in a combination of multiple states at the same time.

The observation of a quantum particle in one definite position at a time.

If a qubit is in the state $|q\rangle = \frac{1}{\sqrt{3}} |0\rangle + \sqrt{\frac{2}{3}} |1\rangle$, what is the probability of measuring the qubit in the state $|0\rangle$?

The probability of measuring the qubit in the state $|0\rangle$ is $\frac{1}{3}$.

The probability of measuring the qubit in the state $|0\rangle$ is $\frac{2}{3}$.

The probability of measuring the qubit in the state $|0\rangle$ is $\frac{1}{\sqrt{3}}$.

You print the qubit's state directly to the console.

You use the DumpMachine function after each operation.

You use the Measure function after each operation.
