Quantum Mechanics on the Hypercube
Abstract
We construct quantum evolution operators on the space of states, that is represented by the vertices of the n-dimensional unit hypercube. They realize the metaplectic representation of the modular group SL(2,Z(2n)). By construction this representation acts in a natural way on the coordinates of the non-commutative 2-torus,T2, and thus is relevant for noncommutative field theories as well as theories of quantum space-time.
