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…

A Universal Protocol for Quantum-Enhanced Sensing via Information Scrambling
Bryce Kobrin, Thomas Schuster, Maxwell Block +4
We introduce a novel protocol, which enables Heisenberg-limited quantum-enhanced sensing using the dynamics of any interacting many-body Hamiltonian. Our approach - dubbed butterfl…
