Steering-enhanced quantum metrology using superpositions of noisy phase shifts [PDF]
Physical Review Research, 2023 Quantum steering is an important correlation in quantum information theory. A recent work [Nat. Commun. 12, 2410 (2021)NCAOBW2041-172310.1038/s41467-021-22353-3] showed that quantum steering is also useful for quantum metrology.

Quantum Metrology in the Finite-Sample Regime
PRX Quantum, 2023 In quantum metrology, a major application of quantum technologies, the ultimate precision of estimating an unknown parameter is often stated in terms of the Cramér-Rao bound.

Experimental super-Heisenberg quantum metrology with indefinite gate order [PDF]
Nature Physics, 2023 The precision of quantum metrology is widely believed to be restricted by the Heisenberg limit, corresponding to a root mean square error that is inversely proportional to the number of independent processes probed in an experiment, N . In the past, some

Quantum metrology with boundary time crystals [PDF]
Communications Physics, 2023 Boundary time crystals are gaining attention due to their distinctive features like persistent oscillations at the thermodynamic limit. This work shows that the boundary time crystal phase transition can be exploited for quantum-enhanced sensitivity ...

Enhanced metrology at the critical point of a many-body Rydberg atomic system [PDF]
Nature Physics, 2022 Interacting many-body systems display enhanced sensitivity close to critical transition points due to diverging quantum fluctuations. This criticality-based enhancement has been suggested as a potential resource for applications in precision metrology ...
