经典系统和量子系统的距离有多远？
How far apart are classical and quantum systems?
摘要：
众所周知，经典系统近似于量子系统--但有多接近呢？我们引入了一个定义的“距离”的经典和量子相空间，提供了一个衡量他们的分离。这种距离尺度提供了一种衡量各种问题近似解质量的方法。一些简单的应用程序进行了讨论。
英文摘要：
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.
