  "abstract": "As is well known, classical systems approximate quantum ones -- but how well? We introduce a definition of a \"distance\" on classical and quantum phase spaces that offers a measure of their separation. Such a distance scale provides a means to measure the quality of approximate solutions to various problems. A few simple applications are discussed.",
