论文摘要
我们提出了一种方法来测量阵列中任意子原子的量子态，而不会显着干扰未衡量的原子中的量子信息。这个想法是首先将现场选择性原子从量子基础上转移出来，以便一次将两个状态之一放入辅助状态。然后，电磁诱导的透明度（EIT）光将保护大多数状态，而检测光散布在辅助状态下的原子，该原子可以通过角动量选择规则和精心选择的光偏振来免疫EIT保护。这两个状态将依次测量，之后可以将原子重新冷却并返回量子状态。这些测量可能是量子误差校正的基础。
We propose a way to measure the qubit state of an arbitrary sub-ensemble of atoms in an array without significantly disturbing the quantum information in the unmeasured atoms. The idea is to first site-selectively transfer atoms out of the qubit basis so that one of the two states at a time is put into an auxiliary state. Electromagnetically induced transparency (EIT) light will then protect most states while detection light is scattered from atoms in the auxiliary state, which is made immune to the EIT protection by angular momentum selection rules and carefully chosen light polarization. The two states will be measured in turn, after which it is possible to recool and return the atoms to a qubit state. These measurements can be the basis of quantum error correction.
