It is the norm induced by the complex dot product over

C^{2}

:

∣ ∣ ψ ⟩ ∣ = ∣ ∣ ∣ \frac{1 + i}{2} ∣ ∣ ∣^{2} + ∣ ∣ ∣ \frac{1 - i}{2} ∣ ∣ ∣^{2} = ∣ ∣ ∣ \frac{1}{2} + i \frac{1}{2} ∣ ∣ ∣^{2} + ∣ ∣ ∣ \frac{1}{2} + i \frac{- i}{2} ∣ ∣ ∣^{2} = (\frac{1}{2})^{2} + (\frac{1}{2})^{2}^{2} + (\frac{1}{2})^{2} + (\frac{- 1}{2})^{2}^{2} = (\frac{1}{2})^{2} + (\frac{1}{2})^{2} + (\frac{1}{2})^{2} + (\frac{- 1}{2})^{2} = \frac{1}{4} + \frac{1}{4} + \frac{1}{4} + \frac{1}{4} + = \frac{1 + 1 + 1 + 1}{4} = 1
