Quantum-to-classical transition still eludes a full understanding. Out of its multiple aspects, one has recently gained an increased attention—the appearance of objective world out of the quantum. One particular idea is that objectivity appears thanks to specific quantum state structures formation during the evolution, known as spectrum broadcast structures (SBS). Despite that quite some research was already performed on this strong and fundamental form of objectivity, the practical realization of SBS in a concrete physical medium has not been explicitly analyzed so far. In this work, we study the possibility to simulate objectivization process via SBS formation using widely studied nitrogen-vacancy centers in diamonds. Assuming achievable limits of dynamical polarization technique, we show that for high, but experimentally viable polarizations (p > 0.5) of nuclear spins and for magnetic fields lower than ≈20 G the state of the NV center and its nearest polarized environment approaches an SBS state reasonably well.

量子到经典的转变仍然难以完全理解。在它的多个方面中，一个最近获得了越来越多的关注——客观世界在量子之外的出现。一个特别的想法是，由于在进化过程中形成了特定的量子态结构，即频谱广播结构 (SBS)，才会出现客观性。尽管已经对这种强大而基本的客观性形式进行了相当多的研究，但到目前为止还没有明确分析 SBS 在具体物理介质中的实际实现。在这项工作中，我们研究了使用广泛研究的钻石中的氮空位中心通过 SBS 形成模拟客观化过程的可能性。假设动态极化技术的可实现极限，我们表明对于高但实验可行的极化（p > 0.5) 的核自旋和低于 ≈20 G 的磁场，NV 中心及其最近的极化环境的状态相当好地接近 SBS 状态。
