Nonlinearity-enhanced quantum sensing in Stark probes
Nonlinearity-enhanced quantum sensing in Stark probes
Stark systems in which a linear gradient field is applied across a many-body system have recently been harnessed for quantum sensing. Here, we explore sensing capacity of Stark models, in both single-particle and many-body interacting systems, for estimating the strength of both linear and nonlinear Stark fields. The problem naturally …
