Abstract

Spin-squeezed states are a resource for quantum-enhanced precision measurement. However, the theoretical foundations for scalable spin squeezing — where quantum enhancement grows with system size — have only been established for systems exhibiting all-to-all interactions. Now, by unveiling a connection to finite-temperature magnetism, scalable squeezing is extended to locally interacting systems.

具有局部相互作用的可扩展自旋挤压

自旋挤压态是量子增强精密测量的一种资源。然而，可扩展自旋挤压的理论基础--量子增强随系统大小而增长--只针对表现出全对全相互作用的系统建立。现在，通过揭示与有限温度磁性的联系，可扩展自旋挤压被扩展到局部相互作用系统。
