摘要

摘要提出了一种在俘获离子中产生一类非热Fock态混合物的方法。这类状态相对于基态具有明显的计量优势，从而克服了标准量子极限，而不需要在狭窄的电子跃迁上进行完整的边带冷却和fock态制备。该方案包括红边带、测量和制备激光脉冲的循环重复。通过协议的克劳斯映射表示，可以将红色边带脉冲的长度与可以生成的特定状态类联系起来。在数值模拟的帮助下，我们分析了这些状态可以可靠地再现的参数区。

Production of Fock mixtures in trapped ions for motional metrology

Abstract 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.

期刊介绍： Driven by advances in technology and experimental capability, the last decade has seen the emergence of quantum technology: a new praxis for controlling the quantum world. It is now possible to engineer complex, multi-component systems that merge the once distinct fields of quantum optics and condensed matter physics. Quantum Science and Technology is a new multidisciplinary, electronic-only journal, devoted to publishing research of the highest quality and impact covering theoretical and experimental advances in the fundamental science and application of all quantum-enabled technologies.
