标题： Electronic Noise Considerations for Designing Integrated Solid-State Quantum Memories

摘要： 随着量子网络的扩展并部署到研究实验室之外，需要为每个存储节点设计和集成紧凑型控制电子设备。 理解此类系统的性能要求至关重要，尤其是关于可容忍的噪声水平，因为这些规范会极大地影响系统的设计复杂性和成本。 在这里，我们使用一种可以轻松推广到量子硬件平台的方法，基于金刚石中的氮-空位（NV）中心呈现了一个案例研究。 我们建模并实验验证了控制系统中的相位噪声和定时抖动与自旋量子比特环境噪声的综合作用。 我们进一步考虑了不同相位噪声特性对动力学解耦序列保真度的影响。 结果展示了一种根据固态自旋量子比特的相干时间、固有噪声谱和所需保真度来指定集成量子控制信号发生器设计要求的程序。 显示英文摘要

摘要： As quantum networks expand and are deployed outside research laboratories, a need arises to design and integrate compact control electronics for each memory node. It is essential to understand the performance requirements for such systems, especially concerning tolerable levels of noise, since these specifications dramatically affect a system's design complexity and cost. Here, using an approach that can be easily generalized across quantum-hardware platforms, we present a case study based on nitrogen-vacancy (NV) centers in diamond. We model and experimentally verify the effects of phase noise and timing jitter in the control system in conjunction with the spin qubit's environmental noise. We further consider the impact of different phase noise characteristics on the fidelity of dynamical decoupling sequences. The results demonstrate a procedure to specify design requirements for integrated quantum control signal generators for solid-state spin qubits, depending on their coherence time, intrinsic noise spectrum, and required fidelity.
