Interpretation for a positive P representation

Not Accessible

Abstract

We show that a standard "canonical" form of the positive P representation corresponds to the output statistics of a simple measurement model. This result has implications beyond the canonical form, because any positive P representation can be transformed into canonical form. This is significant because it has not been previously recognized that the extra phase-space dimensions required to define the positive P representation have a physical meaning. Thus, we have shown that there is no problem with this representation being nonphysical, e.g., when it comes to stochastic simulations.
