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…
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…
