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…
Intrinsic high-fidelity spin polarization of charged vacancies in hexagonal boron nitride
Wonjae Lee, Vincent S. Liu, Zhelun Zhang +11
The negatively charged boron vacancy () in hexagonal boron nitride (hBN) has garnered significant attention among defects in two-dimensional materials. T…
A strongly interacting, two-dimensional, dipolar spin ensemble in (111)-oriented diamond
Lillian B. Hughes, Simon A. Meynell, Weijie Wu +8
Systems of spins with strong dipolar interactions and controlled dimensionality enable new explorations in quantum sensing and simulation. In this work, we investigate the creation…
