How to Compile A Quantum Bayesian Net
  We show how to express the information contained in a Quantum Bayesian (QB) net as a product of unitary matrices. If each of these unitary matrices is expressed as a sequence of elementary operations (operations such as controlled-nots and qubit rotations), then the result is a sequence of operations that can be used to run a quantum computer. QB nets have been run entirely on a classical computer, but one expects them to run faster on a quantum computer.
