论文摘要
掺杂剂的集合在量子技术中广泛应用。然而，相应设备的微型化受到偶极相互作用的阻碍，从而降低了掺杂密度时的相干性。我们从理论上和实验研究了这一限制。我们发现动态解耦可以减轻但不能完全消除具有强烈各向异性自旋相互作用的晶体中的脱谐。我们的发现可以推广到所有用于量子传感，微波转换和量子记忆的各向异性G因子的量子系统。
Ensembles of dopants have widespread applications in quantum technology. The miniaturization of corresponding devices is however hampered by dipolar interactions that reduce the coherence at increased dopant density. We theoretically and experimentally investigate this limitation. We find that dynamical decoupling can alleviate, but not fully eliminate, the decoherence in crystals with strong anisotropic spin-spin interactions. Our findings can be generalized to all quantum systems with anisotropic g-factor used for quantum sensing, microwave-to-optical conversion, and quantum memory.
