论文摘要
我们通过利用与其他环境的相互作用来分析热浴的统计性质的能力。我们首先表明，在不存在附加环境的标准方案的不同之处，仅仅存在额外的浴室就可以改善歧视任务所引起的修改进化。然后，我们还考虑了连续监视附加环境的可能性，我们详细讨论了如何通过考虑不同种类的相互作用，即不同的跳跃操作员以及与连续同型和照片检测相对应的不同监视策略来详细讨论如何在歧视中获得改进的性能。我们的策略原则上可以在QED设置中实施，并为通过连续监视进一步开发量子探测的方式铺平了道路。
We analyze the capability of discriminating the statistical nature of a thermal bath by exploiting the interaction with an additional environment. We first shows that, at difference with the standard scenario where the additional environment is not present, the modified evolution induced by the mere presence of the extra bath allows to improve the discrimination task. We then also consider the possibility of continuously monitoring the additional environment and we discuss in detail how to obtain improved performances in the discrimination by considering different kinds of interaction, i.e. different jump operators, and different monitoring strategies corresponding to continuous homodyne and photo-detection. Our strategy can be in principle implemented in a circuit QED setup and paves the way to further developments of quantum probing via continuous monitoring.
