我们给出了一个明确的方法来实验确定的演化算子，完全描述了量子力学的黑盒子：一个任意的开放量子系统的动力学。我们证明了这是可能的必要和充分条件，并通过考虑具体的一个和两个量子比特系统来说明一般理论。这些程序可能是有用的实验量子测量，通信和计算系统的比较评估。
We give an explicit way to experimentally determine the evolution operators which completely describe the dynamics of a quantum-mechanical black box: an arbitrary open quantum system. We show necessary and sufficient conditions for this to be possible and illustrate the general theory by considering specifically one-and two-quantum-bit systems. These procedures may be useful in the comparative evaluation of experimental quantum measurement, communication and computation systems.
