单次测量量子系统的基态冷却

Ground state cooling of quantum systems via a one-shot measurement

P. V. Pyshkin, Da-Wei Luo, J. Q. You, Lian-Ao Wu

摘要:

我们证明了存在一族量子系统,通过对耦合到这些系统的环进行单次投影测量,它们可以被冷却到它们的基态。因此,这一证明提出了实现单次测量基态冷却(OSMGSC)的条件。我们还提出了一个通用的程序,找到酉传播和相应的哈密顿实现这种冷却的逆工程技术。

英文摘要:

We prove that there exists a family of quantum systems that can be cooled to their ground states by a one-shot projective measurement on the ancillas coupled to these systems. Consequently, this proof gives rise to the conditions for achieving the one-shot measurement ground-state cooling (OSMGSC). We also propose a general procedure for finding unitary propagators and corresponding Hamiltonians to realize such cooling by means of inverse engineering technique.
