Spin-Squeezing of " 8 Rb via Optical Measurement

Abstract

This project aims to reduce measurement uncertainty in atomic clocks by squeezing the collective spin of atoms. Spin-squeezing reduces noise below the standard quantum limit where precision scales as 1//1V, allowing us to instead approach the Heisenberg limit where it scales as 1/N. We report spin-squeezing of the (F = 2, m = 0) --+ (F = 1, mF = 0… (More)
