I'm trying to make a quantum computing mod for a game, (apologies if the notation is wrong I'm new to QM).
Let's say I have 2 qubits that are both $\frac{1}{\sqrt{2}}(|0⟩ + |1⟩)$ and I put them through a CNOT gate. The result would be
$$A \otimes B = \begin{pmatrix} \frac{1}{\sqrt{2}}\\ \frac{1}{\sqrt{2}} \end{pmatrix} \otimes \begin{pmatrix} \frac{1}{\sqrt{2}}\\ \frac{1}{\sqrt{2}} \end{pmatrix} = \begin{pmatrix} \frac{1}{2}\\ \frac{1}{2}\\ \frac{1}{2}\\ \frac{1}{2} \end{pmatrix}$$
$$\mathrm{CNOT}_{\text{matrix}} (A \otimes B) = \begin{pmatrix} 1 & 0 & 0 & 0\\ 0 & 1 & 0 & 0\\ 0 & 0 & 0 & 1\\ 0 & 0 & 1 & 0 \end{pmatrix} \begin{pmatrix} \frac{1}{2}\\ \frac{1}{2}\\ \frac{1}{2}\\ \frac{1}{2} \end{pmatrix}= \begin{pmatrix} \frac{1}{2}\\ \frac{1}{2}\\ \frac{1}{2}\\ \frac{1}{2} \end{pmatrix}$$
Which I don't believe is an entangled system. Thus, would it in theory be possible to get something in terms of the |0⟩ and |1⟩ for each individual particle? For example, express the individual states of qubit 1 and 2 in the form:
$$\alpha|0⟩ + \beta|1⟩$$
(And if so, how would I determine this?)
