自旋系综精密测量的预示放大

Heralded amplification for precision measurements with spin ensembles

Nicolas Brunner, Eugene S. Polzik, Christoph Simon

摘要:

我们提出了一个简单的预示放大计划的小旋转的集体自旋的粒子系综。我们的协议利用两个基本的原语量子存储器,即部分映射到一个合奏的光,和集体自旋激发转换成光。所提出的方案应该是可实现的与当前的技术,与潜在的应用原子钟和磁力测量。

英文摘要:

We propose a simple heralded amplification scheme for small rotations of the collective spin of an ensemble of particles. Our protocol makes use of two basic primitives for quantum memories, namely partial mapping of light onto an ensemble, and conversion of a collective spin excitation into light. The proposed scheme should be realizable with current technology, with potential applications to atomic clocks and magnetometry.
