Precision assessment in non-Hermitian systems: a comparative study of three formalisms
Javid Naikoo, Ravindra W. Chhajlany, Jan Kołodyński +1
Quantifying measurement precision in quantum systems is vital for advancing quantum technologies such as sensing, communication, and computation. The quantum Fisher information (QF…
Optimized detection modality for double resonance alignment based optical magnetometer
A. Akbar, M. Kozbiál, L. Elson +3
In this work, we present a comprehensive and comparative analysis of two detection modalities, i.e., polarization rotation and absorption measurement of light, for a double resonan…
Zero-field optical magnetometer based on spin-alignment
Adil Meraki, Lucy Elson, Nok Ho +4
Optically-pumped magnetometers are an important instrument for imaging biological magnetic signals without the need for cryogenic cooling. These magnetometers are presently availab…
Precision Limits in Quantum Metrology with Open Quantum Systems
Jan F. Haase, Andrea Smirne, Jan Kołodyński +2
The laws of quantum mechanics allow to perform measurements whose precision supersedes results predicted by classical parameter estimation theory. That is, the precision bound impo…
Fundamental limits to frequency estimation: A comprehensive microscopic perspective
Jan F. Haase, Andrea Smirne, Jan Kołodyński +2
We consider a scenario in which qubit-like probes are used to sense an external field that linearly affects their energy splitting. Following the frequency estimation approach in w…
