Imaginary isn't exactly wrong though. Imaginary co-ordinate results in quantum mechanics correspond to non-physical observations - they "exist" but are unobserved until something squares them into reality.
Same with AC power transfer - the imaginary power doesn't drive the load, but it's quite real because I^2*R turns the term into a real power for resistive losses.

This sounds wrong for three reasons: 1. You can multiply any vector of qubits representing a quantum state by any complex number and it's the same state. 2. Measurement is always with respect to a basis. A result can be measured with 0% probability in one basis, 50% in another, 100% in another. 3. It doesn't take into account interference, so it's missing the whole point of how quantum differs from regular probabilities.
