A hidden variable model for universal quantum computation with magic states on qubits

(joint work with Michael Zurel and Cihan Okay)

We show that every quantum computation can be described by a probabilistic update of a probability distribution on a finite phase space. Negativity in a quasiprobability function is not required in states or operations. Our result is consistent with Gleason’s Theorem and the Pusey-Barrett- Rudolph theorem.
