Engineering spin squeezing in a 3D optical lattice with interacting spin-orbit-coupled fermions

The authors propose a protocol that uses both inter-atomic interactions and laser-induced momentum kicks, normally two undesirable decoherence mechanisms in current 3D optical lattice clocks, to engineer metrologically useful entangled states. Their proposal opens a path to push state-of-the-art quantum sensors at absolute limits of both precision and accuracy.
