Quantum mechanics is well representable as a theory of a new kind of measure: quantum measure. It can be interpreted as a covariant counterpart of its usual consideration. The unit of quantum measure is a qubitand thus all physical quantities share a common fundament, that of quantum information, and all physical processes can be interpreted as computational ones. That interpretation of quantum mechanics is fruitful and heuristic: This can be visualized by an explanation of the Aharonov–Bohm effect.
