Abstract

We present a framework for representing quantum entities in Haskell. States and operators are functional objects, and their semantics is defined --- as far as possible --- independently of the base in the Hilbert space. We construct effectively the tensor states for composed systems, and we present a toy model of quantum circuit toolbox. We conclude that functional languages are right tools for formal computations in quantum physics. The paper focuses mainly on the representation, not on computational problems.
