论文摘要
对于正在进行非马克维亚开放量子动力学的量子系统，我们证明了基于该系统的多时间测量值的层析成像算法，该算法重建了与系统耦合的最小环境，因此系统加上环境经历了统一的进化，并且系统的减少与IT的动力学相同。重建的开放量子进化模型可用于预测系统的任何未来动力学，而当它进一步被认为是与时间无关的。我们定义了非马克维亚开放量子动力学的内存大小和内存复杂性，该动力学表征了重建的复杂性。
For a quantum system undergoing non-Markovian open quantum dynamics, we demonstrate a tomography algorithm based on multi-time measurements of the system, which reconstructs a minimal environment coupled to the system, such that the system plus environment undergoes unitary evolution and that the reduced dynamics of the system is identical to the observed dynamics of it. The reconstructed open quantum evolution model can be used to predict any future dynamics of the system when it is further assumed to be time-independent. We define the memory size and memory complexity for the non-Markovian open quantum dynamics which characterize the complexity of the reconstruction.
