Spin squeezing in an ensemble of nitrogen-vacancy centers in diamond
Weijie Wu, Emily J. Davis, Lillian B. Hughes +10
Spin squeezed states provide a seminal example of how the structure of quantum mechanical correlations can be controlled to produce metrologically useful entanglement. Such squeeze…

Scalable Spin Squeezing from Finite Temperature Easy-plane Magnetism
Maxwell Block, Bingtian Ye, Brenden Roberts +7
Spin squeezing is a form of entanglement that reshapes the quantum projection noise to improve measurement precision. Here, we provide numerical and analytic evidence for the follo…
