论文摘要
我们提出了一种在被困离子中产生一类非热的Fock状态混合物的方案。这类状态在基态方面具有明显的计量学优势，因此克服了标准的量子极限，而无需在狭窄的电子过渡上进行全边带冷却和Fock状态准备。该方案包括循环重复红色边带，测量和制备激光脉冲。通过协议的kraus映射表示，可以将红色侧带脉冲的长度与可以生成的特定状态类别相关联。在数值模拟的帮助下，我们分析了可以可靠地再现这些状态的参数制度。
We present a protocol to produce a class of non-thermal Fock state mixtures in trapped ions. This class of states features a clear metrological advantage with respect to the ground state, thus overcoming the standard quantum limit without the need for full sideband cooling and Fock-state preparation on a narrow electronic transition. The protocol consists in the cyclic repetition of red-sideband, measurement and preparation laser pulses. By means of the Kraus map representation of the protocol, it is possible to relate the length of the red sideband pulses to the specific class of states that can be generated. With the help of numerical simulations, we analyze the parametric regime where these states can be reliably reproduced.
