Qubit 2 (5 min)

We assume that the above qubit is realized as a particle that can tunnel between two regions of space 0 and $1$. What is the probability to find it in region 0 (state $\vert\rangle$) if the qubit is in the quantum state

$$\frac{1}{\sqrt{2}}\left( i \vert\rangle -1 \vert 1\rangle \right),\quad i=\sqrt{-1} ?$$
