We have a qubit in the state $|\psi \rangle= √3/2 |0\rangle + 1/2 |1\rangle$, which we want to measure in the $cos \theta\ |\theta\rangle + sin \theta |1\rangle, sin \theta |\theta\rangle - cos θ |1\rangle$ basis. In order for the two possible outcomes to be equiprobable, what should be the value of $\theta$ in degrees?
