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.
