Laser-enhanced quantum sensing boosts sensitivity and dynamic range
Florian Schall, Lukas Lindner, Yves Rottstaedt +8
Magnetometers based on nitrogen-vacancy (NV) centers in diamond have emerged as the most important solid-state quantum sensors. However, ensembles are limited in optical contrast t…
Quenching Speculation in Quantum Markets via Entangled Neural Traders
Kieran Hymas, Hiu Ming Lau, Kareem Raslan +5
Speculative trading can drive pronounced market instabilities, yet existing regulatory and macroprudential tools intervene only after such dynamics emerge. Quantum technologies off…
Quantifying the advantage of vector over scalar magnetic sensor networks for undersea surveillance
Wenchao Li, Xuezhi Wang, Qiang Sun +2
Magnetic monitoring of maritime environments is an important problem for monitoring and optimising shipping, as well as national security. New developments in compact, fibre-couple…
Nitrogen-Vacancy Emission from Nanodiamond: Size, Depth, and Surroundings
Harini Hapuarachchi, Francesco Campaioli, Jared H Cole +2
The negatively charged nitrogen-vacancy (NV) center in diamond is a leading solid-state quantum emitter, offering spin-photon interfaces over a wide temperature range with applicat…
A fluorescent color center in meteoritic Lonsdaleite
Giannis Thalassinos, Alan G. Salek, Daniel Stavrevski +7
Lonsdaleite -- hexagonal diamond -- has only recently been proposed as a wide-bandgap host capable of supporting optically active point defects, but no such centres have yet been o…
Nitrogen-vacancy centre in lonsdaleite: a novel nanoscale sensor?
Anjay Manian, Mitchell O. de Vries, Daniel Stavrevski +3
Hexagonal diamond, often called lonsdaleite, is an exotic allotrope of carbon, predicted to be harder than cubic (conventional) diamond with a wider bandgap. Due to its pure sp…
