Utilizing Ramsey interferometry, the researchers confirmed that the phase measurement sensitivity approached the Heisenberg limit. This long-lived Schrödinger-cat state paves a new way for atomic ...

The most well-known “classical” sensing protocol is Ramsey Interferometry, which allows one to measure an unknown frequency. Recently, a Ramsey Interferometry-based Iterative Adaptive Sensing (IAS) ...

On the other hand, Vedral and his coauthors' proposal uses Ramsey interferometry of a single probe qubit within a trapped ion experiment. Both methods have the same goal: to measure the work ...

The QSL was applied to the canonical sensing principle of Ramsey interferometry. Ramsey interferometry's canonical quantum sensing scheme utilizes two state transformations to start and halt a ...
