Quantum Enhanced Dark-Matter Search with Entangled Fock States in High-Quality Factor Cavities

ORAL

Abstract

Distributed quantum sensing with high-quality factor cavities hold great promise in dramatically improving detection efficiency and reducing background noise in dark matter searches. We propose a dark matter sensing protocol for high-quality factor superconducting radio frequency cavities; leveraging the combined properties of entanglement, stimulated emission and long signal accumulation times. These properties enable unprecedented scaling, quadratic with respect to the number of cavities in the entanglement scheme and linear to the initialized quantum number. We rigorously model the effects of the decoherence from realistic noise channels within our protocol, via both numerical simulations and analytical derivations. Finally, we discuss methods to implement this protocol experimentally.
