Human perception like thinking seems to be essentially synthetic. We never perceive an object by scanning it point by point. We instead form right away a Gestalt, i.e. a global idea of it. Rational activity, as well, seems to be essentially based on gestaltic patterns. Quantum computation has suggested a new holistic semantics, which makes essential use of the characteristic “holistic” features of the quantum‐theoretic formalism. In this framework, meanings are represented by quantum information quantities: systems of qubits or, more generally, mixtures of systems of qubits. The global meaning of a compound expression (which may correspond to an entangled state) determines the meanings of its parts, but generally not the other way around.
