Ultimate sensitivity of multiparameter estimation in quantum sensing with undetected photons
Sanjeet Swaroop Panda, Lorcan O. Conlon, Li Gong +4
Quantum sensing with undetected photons is a technique where photons of one wavelength probe a sample, but information is extracted by measuring photons of another wavelength that…
Spin Correlations in Recirculating Multipass Alkali Cells for Advancing Quantum Magnetometry
Qian Ling Kee, Lingyi Zhao, Ruvi Lecamwasam +6
Multipass cells enable long optical path lengths in compact volumes and are central to quantum technologies such as atomic magnetometers and optical quantum memories. In optical ma…
Microscopic theory of a precessing ferromagnet for ultrasensitive magnetometry
Xueqi Ni, Zhixing Zou, Ruvi Lecamwasam +5
Levitated systems have great potential in quantum sensing and exploring quantum effects at the macroscopic scale. Of particular interest are recent works suggesting that a levitate…
The relative entropy of coherence quantifies performance in Bayesian metrology
Ruvi Lecamwasam, Syed M Assad, Joseph J Hope +3
The ability of quantum states to be in superposition is one of the key features that sets them apart from the classical world. This `coherence' is rigorously quantified by resource…
Feedback Cooling of an Insulating High-Q Diamagnetically Levitated Plate
S. Tian, K. Jadeja, D. Kim +6
Levitated systems in vacuum have many potential applications ranging from new types of inertial and magnetic sensors through to fundamental issues in quantum science, the generatio…
Quantum metrology with linear Lie algebra parameterisations
Ruvi Lecamwasam, Tatiana Iakovleva, Jason Twamley
Lie algebraic techniques are powerful and widely-used tools for studying dynamics and metrology in quantum optics. When the Hamiltonian generates a Lie algebra with finite dimensio…
