有限资源下的量子系统表征

Quantum system characterization with limited resources

Daniel Oi, Sophie Schirmer

摘要:

大规模量子信息器件的构建和运行提出了巨大的挑战。一个主要的问题是相干进化的有效控制,这需要准确的系统动态知识,可能会因设备而异。我们审查策略,从最小的初始资源,并在一个有效的方式获得这样的知识,并将这些嵌入到一个更大的状态流形的量子位的表征问题,通过利用先前的结构知识变得易于处理。我们还研究了自适应采样估计的多个参数。

英文摘要:

The construction and operation of large scale quantum information devices presents a grand challenge. A major issue is the effective control of coherent evolution, which requires accurate knowledge of the system dynamics that may vary from device to device. We review strategies for obtaining such knowledge from minimal initial resources and in an efficient manner, and apply these to the problem of characterization of a qubit embedded into a larger state manifold, made tractable by exploiting prior structural knowledge. We also investigate adaptive sampling for estimation of multiple parameters.
